Den har det siste året tatt oss med på en rekke spennende reiser. Gode foredrag, spennende diskusjoner og mange sosiale kvelder. I år har vi i crewet på raketten igjen gått inn for landing her ved Oslo Spektrum. Her har vi startet med å etablere en forskningsstasjon hvor vi de to kommende dagene skal forske, eksperimentere og evaluere resultatene vi har oppnådd siden vi var her sist. Vi har samlet Norges beste utviklere Et slikt prosjekt, en slik reise, hadde ikke vært mulig å gjennomføre uten et så kompetent mannskap og så dyktige foredragsholdere og samarbeidspartnere. Det synes jeg vi virkelig skal dra nytte av. Bruk dagene til å diskutere og lære av dine kolleger. javabin har derfor dedikert 40 m2 av standen sin til et område fylt med whiteboards og skjermer. Ved disse er alle hjertelig velkommen til faglige diskusjoner. I tillegg utfordrer jeg alle foredragsholdere til å fortsette spørsmålsrunden i dette området. JavaZone stopper Java-Norge Oppslutningen rundt JavaZone har fra 2002 vokst år for år. Konferansen har etter hvert satt betydelige spor i markedet. Jeg vil sitere Thor Henning Totto Hetland helt tilbake til 2005: Arrangementet har nå blitt så stort at mange Java-prosjektetene står bom stille de dagene konferansen pågår. Det året var vi bare 1000 utviklere. I år er vi godt over Til sammen setter vi godt over 20 årsverk på hold for nervøse, engasjerte og fortvilte prosjektledere. Dette vil jeg selvsagt kun snu til det positive, siden alle kommer tilbake opplyst og engasjert fra Norges mest effektive kunnskapsutveksling. Code, sweat and tears Å arrangere verdens tøffeste utviklerkonferanse koster blod, slit, kode og tårer, men det er først og fremst et stort privilegium å få være med på. De mange frivillige som til sammen legger ned titusenvis av frivillige timer for å gjøre disse to dagene så innholdsrike, har alle forskjellige interesser, og dermed ulike arbeidsoppgaver. Vi leser, koder, evaluerer og planlegger. Kom innom javabin-standen for å høre hvordan nettopp DU kan gi ditt unike bidrag til JavaZone eller et av javabins mange andre prosjekter. Før vi setter kurs, vil jeg benytte anledningen til å rette en stor takk til alle som har bidratt til JavaZone Alle javabin-helter, våre 45 partnere, teknisk leverandør Macsimum og alle våre frivillige funksjonærer. Lykke til på ferden!

Implementing such a dynamic and rich model, is not easy with an Object Oriented language like Java. The proposition of the authors, is that one can assist composing a song from audio fragments with the help of simple heuristics. Given that the audio is tagged with human recognisable information such as verse, refrain, lyrics, speed, starting and ending points. Storing such diverse information in a Topic Map is fairly trivial, but creating a dynamic Java model which can represent this is not, and the talk will discuss this topic further. The audience will be introduced to simple concepts of Topic Maps and music composition theory. The talk will finally present Vaudeville, the deliverable of the Customer Driven Project, made by students at NTNU. Vaudeville showcases Java technologies, assisted music composition and other concepts behind the project.

Basic knowledge of Object Orientation is preferred. Java 6 update 10, ease of deployment and Java SE 7 Raghavan N. Srinivas, Sun Microsystems Lab 2, Onsdag kl. 14:15 Java SE is on over 90% of desktops and Java ME is on over 90% of mobile phones. Java is also making a big dent in the consumer space such as set top boxes, Blu-Ray Disc players and so on. Although Java client technology is ubiquitous, consumer applications are not because development and deployment for consumers is still too hard. The talk will explore the features that are being explored to create leaner and meaner JRE that eases deployment and installation. The features that are being looked into will ease start-up time, provide a quick launch and on-demand installation, among other things. The talk will explore the Java Kernel and other features that ease applet and application instantiation and deployment. We will also look at features that enable building richer client applications with Java SE 6 Update 10. The talk will also look into features of Java SE 7. After attending this session attendees should be able to walk away with a good understanding of where the Java SE platform is headed and how this should ease their development and deployment concerns for consumers. Building the Big Brother of the Java Virtual Machine Paul René Jørgensen, senior consultant, Telenor Steinar Cook Lab 2, Onsdag kl. 15:45 Did you ever want to be the Big Brother of the Java Virtual Machine? Being able to do non intrusive monitoring of method calls without access to the source code, performing this in a production environment without a noticeable performance hit? Do you want to know who is doing what to whom, that is, who invokes what method in context of which principal? Making certain that memory consumption is dynamically adjusted to avoid out of memory situations? Would you also like to use it in your legacy applications running pre Java 5 as well as utilize the new Java agent interface of the newer JVMs? You know you have to collect vast amount of data and process it effectively and in real time. Finally you figure out that the amount of data exceeds the capabilities of a traditional data model and you decide that the only solution is a dimensional data model, using MDX for multi dimensional analysis. There are numerous tools available for profiling and measuring your Java programs. However these tools are either: a) aimed at profiling or measuring your code in a development environment; b) expensive; c) not open source; d) requires a Ph.D. in debugging and profiling e) any combination of the above :-) Usemon (usemon.org) attempts to alleviate this by providing an open source tool which is easy to use, collects data from environments based upon Java 1.4 through 6, has a flexible dimensional data model stored in a SQL database and attempts to be non-intrusive. Usemon hooks into the Java virtual machine through a modified class loader on older JVMs or via the Java Agent Interface from version 5 and up. It automatically monitors Java EE components (EJBs, Servlets, MDBs, Queues, SQL Statements, etc), but can be configured to inspect any class in your JVM. Data is multicasted from agents to one or more collectors and stored in the DBMS of your choice. Usemon comes with a complete configuration for MySQL. The overhead of running Usemon is negligible and thus you may collect run-time statistics around the clock all year, which is rather fascinating, given that you have enough disk space. Usemon was developed for large Java EE environments at Telenor, which is one of the worlds largest telco to fulfill these requirements. You may utilize it in any environment in which you have control over the Java Virtual Machine start up parameters. For example Java EE Side 24 Side 25

Q&A Hard core developers with interest in performance and run time dependencies. Better Domain Driven Design Anders Norås, seasoned software developer and speaker Lab 3, Onsdag kl. 14:15 One of the core principles of domain driven design is that it should be focused on the domain and it s logic, rather than the technology used to implement the system. However, many projects using the domain driven approach get tangled up in the technicalities of software development which increases complexity, reduces velocity and hurts both maintainability and reusability. In this talk I will demonstrate how to employ software engineering principles like Don t Repeat Yourself (DRY), the single responsibility principle, separation of concerns and many more to keep attention on the model and at the same time cater for the concerns that clutter the designs of many domain driven solutions. After attending this talk, you should have a better understanding of how to separate your infrastructural con- cerns from your domain logic, build adaptable domain models that fit into many usage scenarios and keep those models maintainable throughout the entire project life-cycle. Introduction. This section is just a brief introduction to the ensuing topics. ~2 minutes. When Patterns Become Anti-patterns. This section will show how we unconsciously collapse our ap- plication structures by using design patterns to increase flexibility and let rigidity creep in to our designs. ~5 minutes. The Strategy Pattern. The Strategy pattern enables us to select algorithms at runtime, but this comes with at the cost of forcing classes to have knowledge about the contexts in which these algorithms are used. Focusing on the implementation of a commonly used pattern drives attention to- wards how we can implement the same pattern with different means, which will be one of the themes for the rest of the talk. The Collapse of Application Structure. Our implementations of common design patterns causes a -pattern lock-in that can fragment domain logic and blur out the distinction between domain and in- frastructure logic. This can hurt the maintainability of our applications. Making Roles Explicit. This section will focus on improving the design of a domain model s internals to achieve better separation of concerns and improved flexibility and maintainability. ~15 minutes Our Objects Play Too Many Roles. Our domain objects, especially Aggregates, often violate sound software engineering principles. The upside of this is that it gives developers using these a better experience, the downside is that it hurts maintainability. In this section I will show how the common validation patterns we use in our models violates the sin- gle responsibility principle and eschew domain concepts. Refactoring to Explicit Roles. In this section I will show how to separate the concerns in the previ- ous section into domain objects and services that adhere to the single responsibility principle and makes the solution more extensible. Data Access is Infrastructure. This section will focus on improving the architecture of an application by clearly distinguishing between domain logic and infrastructure code. Towards the end we connect the dots by combining the lessons from this section with the ones form the previous section. ~20 minutes Don t Repeat Yourself! In domain driven design we use Repositories to abstract the data access layer. Different Repositories often share the same behavior and their implementations often violate the DRY principle. In this section I will show how to refactor the repository concepts into an applica- tion s supporting infrastructure to increase productivity, reusability and maintainability without sacrific- ing the flexibility of hand-rolled repositories. Lazy About Lazy Loading. Repositories are commonly used in conjunction with object/relational mappers to increase separation of concerns. As the real-world concerns of software development manifest themselves, these abstractions start to leak and soon our domain services get tainted with fetching strategies and similar. In this section I will show how we can combine the concepts from pre- vious sections with Inversion of Control to keep our models clean. Wrap up. In this section the emphasis is on separation of concerns, the DRY-principle and the importance of keeping roles explicit. ~5 minutes Attendants should have at least a basic understanding of domain driven design to get full yield. The design principles and techniques presented are generally applicable, and can be of interest to attendants with out experiences with domain driven design. This talk is directed towards developers and architects who practice or want to practice domain driven design. It should also be of interest to domain driven design skeptics who feel that this practice. Latest debugging techniques for Swing applications Maxim Zakharenkov, Exigen Inc. Lab 3, Onsdag kl. 18:15 Debugging of Swing application is not always easy because it is visual toolkit and in many cases you can not just write an automated test that checks if your UI looks good, all components have right sizes, all necessary information is visible and painting done correctly. The presentation will cover some common difficulties connected to visual nature of Swing toolkit and provide fast solutions for solving them using Swing Explorer tool developed as open source project You will learn how to answer the following questions: Which component painted this pixel? In which line of code? Does your application access Swing from the correct thread? How does Swing perform painting step by step? And even more... If you are experienced or beginner in Swing and want to increase your productivity this session is for you. The session is going to present the latest debugging know hows appeared this year.

Riktig feilhåndtering (og ja, checked exceptions er skadelige) Trond Arve Wasskog, developer and CTO, Bekk Lab 5, Onsdag kl. 13:00 Etter mange tiår med programvareutvikling skulle man tro at de fleste applikasjoner håndterer feil på en god måte. I realiteten blir exceptions slukt, kastet på nytt, innpakket, ignorert og tilfeldig logget - om de i det hele tatt er tenkt på. Denne sesjonen viser tilnærminger som fungerer og noen tommelfingerregler for feilhåndtering, samt fallgruver og grusomme eksempler. Vi diskuterer også checked exceptions - et eksperiment i Java - og forklarer hvorfor de bør unngås. Feilhåndtering generelt og i Java spesielt Overordnede tilnærminger Distribuert - Lettvekts exception-hierarki Sentralisert - Få felles exception-typer Exception-typer - Applikasjonsfeil og systemfeil Feilhåndtering er viktigere enn feilretting Checked exceptions er skadelig og bør unngås Sånn, ikke sånn Bruk eksisterende exceptions Ikke sluk exceptions Fallgruver med try-catch-finally Deklarasjon av exceptions i metodesignaturen Russisk kone-exceptions Håndtering av stacktrace Unngå både logging og kasting Logging for overvåkning, drift og forvaltning Exception kontekst, feilkoder og instans-id Navngiving, moduler og pakking Testing av exceptions Required experience Only Java programming knowledge is required. Expected audience This will be a techy session targeting developers and architects. Fra kildekode til bytecode - Implementering av egne språk for JVMen Kristian Nordal, Java-utvikler, Arktekk Trygve Laugstøl, utvikler/arkitekt, Arktekk Lab 6, Onsdag kl. 09:00 Alternative språk til Java som kjører på VMen er i vinden om dagen. Groovy, Jython og JRuby er eksempler på populære språk som fler og fler eksperimenterer med, og som bransjen er iferd med å ta i bruk. Felles for disse språkene er at kildekoden blir kompilert til Java Bytecode før den kan eksekveres på JVMen. Målet med dette foredraget er å gi en oversikt over veien fra kildekode til kjørende bytecode. Dette foredraget starter med en rask gjennomgang av kompilatorteknikk, etterfulgt av en gjennomgang av den fullstendige implementasjonen av et enkelt eget-utviklet språk - som kjører på JVMen. Vi vil forklare hvordan vi parser kildekoden og sjekker syntaktisk korrekthet. Neste steg blir å vise hvordan man genererer Java assembly-kode, som vi deretter bruker for generering av eksekverbar bytecode. Foredraget vil være en teknisk sesjon, med live-demoer av kjernekonseptene. Vi vil runde av foredraget med en kort diskusjon av mulige motiver for å ville utvikle egne språk for VMen. Kompilatorteori Fra kildekode til bytecode - Lexing - Bygging av AST - Semantikk - Generering av bytecode Motivasjon (5 min) Oppsummering Language: Norsk Required Experience: Deltakerne vil ha en fordel av god forståelse av JVM-plattformen. Expected Audience: Utviklere som er nysgjerrige på hvordan språkene til plattformen vi jobber på til daglig fungerer. Side 26 Side 27

15 Core Java Technologies, AOP, POJO and research Core Java Technologies, AOP, POJO and research Bytecode Manipulation in the Real World Geert Bevin, CEO, Uwyn Lab 6, Onsdag kl. 10:15 Byte code manipulation has become increasingly popular over the last years. It is used by JPA implementations, application servers, AOP libraries, web frameworks, monitoring systems, profilers, clustering solutions, scripting languages, workflow engines, and much more. In fact, most of today s applications will most probably rely on byte code manipulation, often even without realizing. Application developers however seem to be overly careful and often frown upon byte code manipulation as an arcade art that is risky and difficult to understand. This presentation will show you that it s easier than you think. We ll go over concise examples that illustrate the concepts. Distinct patterns, coming from different domains, will give you ideas about adopting byte code manipulation for your own products. You ll learn arguments to reassure skeptics and see how the manipulation can plugged into your tool chain. We ll finish off with tips and tricks to write maintainable code with the ASM library. After this session you ll see byte code manipulation as another tool in your arsenal and you ll have a good picture of how to start using it yourself. Introduction What is byte-code manipulation? Popular projects and what they use it for Don t be afraid Plugging in the manipulation Code examples from open-source projects using ASM Tips, tricks and gotchas Q/A Language: English Environment aware spring context Kaare Nilsen, principal consultant, Arktekk Lab 6, Onsdag kl. 14:15 When the Spring framework hit the marked, it revolutionized the way we build our applications. Dependency injection, and inversion of control became well known terms, and it is difficult to imagine how we managed without them. But there is one aspect of the Spring framework that has been fiercely discussed for a long time; What is the best approach to configuring our applications for deployment in multiple environments? I have struggeled with this problem since my first encounter with the Spring framework, and over the years I have tried just about all the techniques there are. Some of them turned out to be bad - some of them turned out to be really bad. In this talk I will go through some of the techniques and approaches I have tried, and discuss their strengths and weaknesses. Based on these trials and errors, I have put together a framework that aims to enhance the Spring container - enabling it to be differently configured for different target systems. I will demonstrate how you can use this framework to make your applications dramaticly easier to configure, easier to test, and less prone to malconfiguration in production and test environments. The ultimate goal Configuration techniques that failed miserably - Using your build system for resource filtering - JNDI as configuration repository - Commons Configuration - The evil PropertyPlaceHolderConfigurer Introducing the Stage Enabled Spring Contexts project - Brief introduction to annotation based configuration in Spring - Choosing implementation of services based on the running environment - Increase testablility - Configuration options - Handling property files Customization options Q&A Language: English Attendees will be expected to be experienced Java programmers with fairly good knowledge of the Spring framework. Experience with large scale enterprise applications would be a benefit. This session targets software architects and software developers, working on Spring based enterprise applications. Swing Application Framework: One Year Later Harald Kuhr, senior developer, Escenic AS Yngvar Sørensen, senior consultant and Swing expert at Bouvet ASA Lab 6, Onsdag kl. 15:45 In this talk we will attempt to summarize and share our experience from one year of developing commercial grade applications using JSR 296: Swing Application Framework. We will thoroughly cover the basics of Swing Application Framework, and dive into the most useful features, some best practices and potential pitfalls. Finally, we will reflect on the current state and future of SAF. The talk will act as a follow up on last years Building Real Swing Applications, where we covered the fundamentals of building Swing applications. With more than twenty years of Java experience between them, this presentation will be given by Escenic s Harald Kuhr, lead developer of Escenic Content Studio, and Bouvet s Swing expert Yngvar Sørensen. Language: Norwegian (slides in english) Basic Swing programming Swing developers interested in learning about Swing Application Framework Comparing IoC containers (Spring, Guice, Tapestry 5 IOC, HK2) Peter Norrhall, System architect Niclas Nilsson, Software development coach, consultant, educator and writer Lab 6, Onsdag kl. 17:00 This session will compare a range of popular IoC containers. The containers that will be compared are: Spring, Guice, Tapestry 5 IOC, HK2 Summary: Many Java developers have used a IoC container - or at least heard about Spring. Today there are a good number of IoC containers and each of them claiming to do Dependency Injection (DI) in a better way. This session will explain what IoC/DI really is, why we should use it, how the containers work and when to use each specific container. In this session, you will learn: What Dependency Injection can add to your applications; How various frameworks, including Spring, Guice, Tapestry 5 IOC, HK2 and PicoContainer, work; Tips on when to use each specific container. Knowledge of an IoC container People eager to know more about IoC containers Achieving greater code reuse through decoupling of feature implementations from the domain Eitan Suez, independent software developer Lab 6, Onsdag kl. 18:15 In the last several years, I ve taken a different approach to building software applications. Implementing various application concerns(1) generically(2) has enabled me to reuse the implementations across projects. (1) concerns: such as forms construction, validation, ui navigation, search, authorization (2) generically: in such a fashion that the implementation is decoupled from, or agnostic from the application s domain Specifically, I have constructed a framework that enables a very high degree of reuse, whereby I reduce application development to little more than defining the domain. Where implementations of the persistence, user interface, and other concerns can be reused across differing applications. In this talk, I will be sharing with you my experiences with this approach, and the results it has yielded. Live demonstrations of the various reusable features will be given. Introduction What s wrong with the way we build software applications today? The scaffolds we see in rails, grails, etc.. are the beginning Decoupling concerns implementations from the domain = Freedom to reuse implementations across applications How to decouple the model: coupling to the metamodel Demonstrating sample applications constructed in this fashion Overview of Generic Implementations: Generic Create, Read, Update, Delete Deployment Analysis of the results Conclusions/References Q&A Language: English Participants should have experience in designing and implementing business software solutions. Code examples will be given using the following specific tool stack: the Java programming language, the Swing GUI Toolkit, the Hibernate O/R Mapping framework, and Java reflection, metadata concepts. Please consider attending this session if you are either a developer or manager with interest in exploring ways to improve the current state of software applications development in the areas of: developer productivity, usability, software application maintainability. Objects of Desire Kevlin Henney, independent consultant Lab 1, Torsdag kl. 10:15 Given that object orientation underpins the Java language, it would be expected that anyone using Java would also know about OO. In one sense this is true, but there is more to effective modern object-oriented development than just creating a few objects and calling a few methods. Many developers working in Java have not had the opportunity or exposure to effective object-oriented practice that would allow them to avoid common design pitfalls and to make more effective use of the language. Although object orientation is far from being a new approach (think Sergeant Pepper), and it s also far from being obscure, its mainstream adoption by programmers and programming languages alike is not always as effective as it could be, and sometimes the results can be less than desirable (to put it politely). This session aims to put a number of concepts many developers may be unsure of on a firmer footing, highlighting common pitfalls in OO practice -- such as abuse of inheritance, simplistic getter/setter interfaces, patternitis, use of singleton objects -- and emphasising techniques that promote an easier life -- such as loose coupling, unit testability, pattern-based design thinking, incremental and sufficient design.

16 Core Java Technologies, AOP, POJO and research Core Java Technologies, AOP, POJO and research Clean Code III: Functions Robert C. Martin, founder and president, Object Mentor Inc. Lab 1, Torsdag kl. 13:00 Get ready for a challenge as Robert Martin dives deep into the topic of clean Java code by examining what makes a good function. In this talk we will look at a lot of code; some good and some bad. We will experience how such code is analyzed, critiqued, and eventually refactored. We will understand the decisions made by an expert in the field as bad code is gradually transformed into good code. How big should a function be? How should it be named? How should it be documented. How many indent levels should it have? How should it deal with exceptions, arguments, and return values. This talk is all about code at the lowest level. And yet the principles and techniques presented have far reaching implications. Easy and maintainable enterprise testing with Unitils Filip Neven, architect, Ordina Belgium Lab 2, Torsdag kl. 13:00 Unit testing has become a mainstream task. Most developers do it. Most project leaders and architects expect their team to write tests. However, practice has taught us that a lot of teams write few tests, or spend too much time writing and maintaining them. Different development teams make common mistakes, run into similar issues and find their own solutions for them. This costs a lot of valuable time. Unitils started in 2005, when a group of developers and architects joined in a task force to share their testing experience. These discussions resulted in a set of testing guidelines. The leaders of this task force started writing code to help implementing these guidelines. Unitils has emerged from concrete experience and lessons learned, with the ultimate goal of making unit testing easy, effective and maintainable. Unitils offers a lot of support in testing the database layer: automatic maintenance of test databases, automatic post-processing of the database to make it more testfriendly, loading test data using DbUnit and verifying the contents of the database after execution of a test. Unitils provides specific support for testing with JPA or hibernate, and offers integration with spring. It makes abstraction of the testing framework that is used for executing the tests, making it useable with JUnit3, JUnit4 or TestNG. But Unitils is not limited to persistence layer testing only: The reflection assert utility is a very useful alternative to the classic assertequals method with a range of leniency options. Unitils also provides superior support for dynamic mock objects, offering a simple syntax for specifying method behavior and verifying expectations. During this talk, I will present the different features of Unitils using simple, concrete examples. I will talk about problems from real projects and demonstrate how Unitils helps solving these problems. Introduction Feature overview: Using examples, I ll demonstrate the features of Unitils: assertion using reflection, test data management, test database maintenance, JPA / hibernate and spring integration, testing with mock objects. Demo: demonstration of the database maintainer, JPA / hibernate entity-database mapping test Architecture: Provide some insight into how Unitils works. Summary and roadmap: What are our plans for the future Q & A Basic experience with unit testing. Knowledge of hibernate and spring is useful but not required. Developers, technical project leaders and architects, who are into unit testing and want to improve testing on their projects. Zero Turnaround in Java Development Jevgeni Kabanov, R&D, Webmedia Ltd Lab 5, Torsdag kl. 13:00 Turnaround is the time it take for the changes in code to propagate to the running application. It includes build time, deploy time and initialization time. Recently some developments in the Java ecosystem and IDEs made it possible to develop software with zero turnaround. This talk is an overview of these developments, which include dynamic languages like Groovy, JavaScript and JRuby, framework support for reloading like Tapestry 5 and RIFE, module approach in OSGi and generic class reloading approaches like HotSwap, JavaRebel and FastSwap.With each approach we discuss benefits and limitations. We also review how to set up your build environment to get least possible turnaround whether you program legacy code or start from scratch. Intro [5m] Dynamic languages [15m] Modular approach [5m] Framework reloading support [5m] Class reloading [10m] HotSwap JavaRebel & FastSwap Setting up your environment [10m] Exploded development Build cycle Symbolic links and junction points Q&A [10m] Required experience Familiarity with the Java development cycle. As an overview talk the goal is to show the possible options rather than discuss each of them in depth. Expected audience Software engineers and architects who want to improve their development turnaround time. The talk is based on experience of decreasing development time of 150 developers to almost zero. A lot of that expirience can be directly transferred to you. Software and Metrics Is quality measureable? Recipes to reach bettertechnology quality! André Fleischer, software architect, Otto group Lab 5, Torsdag kl. 14:15 What is internal quality and why are metrics helpful? A comparison with a cake will make it easy to understand: Not the optic and not the frosting on top of a cake guarantee a good taste and a healthy enjoyment. The ingredients, the recipe, the baking itself, the enjoyment of the cake, the great treat of it to keep in memory and the comfortable feeling afterwards are part of the total value and quality of the tasty cake. With the enjoyment of software is it likewise. The inner quality of software is crucial for your success in software development projects. This talk gives answers why this kind of quality is so important and how to gain better technical quality using different metrics based on the usage of the open source software XRadar (and others). The quality of software can be divided into two parts. The first part is the outer quality, also known as functional quality. This is the quality seen by the user of the software. The second part is the internal quality, also known as technical quality. This is the quality seen by the software engineers. The testing of software is often only based on functional testing. Because the functional testing is driven by the functional requirements, the functional quality is easy to test and easy to measure. The technical part of the software is almost ignored, because the technical quality is harder to test. But the technical quality directly affects the functional quality. Sometimes you have non-functional requirements like response time for a certain function, but other non-functional requirements, like maintainability, are not measured. The talk will give the attendees ideas how to test or measure the technical quality of their software. I will give answers concerning basic questions on software quality, source code, object model, software metrics and their relationship. I will give a short introduction into basic terms and I will give a short overview on basic metrics and metrics on a higher, aggregated level. Then I will show some open source tools like PMD, ckjm, JDepend and will discuss the usage problems. Tools like SonarJ, Sonar and Xradar have more benefits. They consolidate the basic reports of the basic tools to create more readable and understandable reports of your software. The talk will have a focus on practical methods. I will also give examples based on daily project practice and the usage based on the open source tool XRadar (xradar.sourceforge.net). XRadar is a toolkit for quality analysis for java based software project. It is a reporting tool based on many other open source toolkits like PMD or JDepend. Motivation (5min) o Why do we need to control quality? o What big problems do we face when developing software? What is technical Quality? (5min) o Definition of basic terms o What is quality, what is technical quality o What are metrics? How to measure Quality! (5 min) o Introduction of different metrics o Introduction of methodologies o Basic to find quality criteria for your project. o Why it is important to have good tools (Example: XRadar) Implementation within project ( 10min ) o How to do measurement within software development process o Showcase for some basic tools like PMD, ckjm etc. (Examples) o Why do we need good integrated tools Comparison of different integrated tools (15min) o Comparing XRadar with other tools o Showing the pro s and con s of different tools XRadar SonarJ Crap4J Sonar o Showing the usage of tools Xradar SonarJ Conclusion (5 min) o Giving pro s and con s for controlling technical quality o Giving references to further reading, links, tools o Will give a summary of basic action steps. Required experience The attendees should have experience what could happen if they have bad quality within their projects Expected audience Technical project leads, software architects and all people who are in charge for delivering good quality to your customer. The participants will learn why they should monitor the technical quality. The will get an introduction into the basic methodologies as well as best practices. They will be able to start increasing their technical quality right after the talk. Adding Animation and Media to Java Applications Raghavan N. Srinivas, CTO of Technology Evangelism, Sun Microsystems Lab 6, Torsdag kl. 11:45 Rich Applications has achieved a new degree of sophistication with requirements to add multimedia and animation. With the introduction of the new JavaFX SDK and Java SE 6 update N, it is possible to incorporate the newer elements of a very rich client application into new and existing Java applications. Attend this session to get a very brief overview of the JavaFX programming language and the animation and media APIs that make it possible to create some sexy looking GUIs which was hitherto difficult in Java. After attending this session, attendees will walk away with a good understanding of JavaFX and Java SE 6 Update N and how to incorporate the features, such as audio, video and animation into their applications. They will also get an idea of the deployment options i.e. applets or applications. Overview of JavaFX 5 mins. Language features (binding, sequences, etc.) 10 min. Animation 15 min.

17 Core Java Technologies, AOP, POJO and research Core Java Technologies, AOP, POJO and research map - reduce og andre teknikker for parallellisering Bjørn Nordlund, sjefskonsulent, BBS Lab 6, Torsdag kl. 13:00 Har du en snikende følelse av at din trygge serielle hverdag er truet og at parallellisering antagelig er noe du bør ha et forhold til før eller siden, da er målet med denne enkle introduksjonen til parallellisering å kunne vise at dette ikke nødvendigvis trenger være veldig vanskelig. Noen ganger har man behov for å splitte opp større jobber for eksempel for å utnytte datakraften som er tilgjengelig over flere prosessorkjerner, prosessorer og servere. Teknikker, infrastruktur og rammeverk finnes for dette, men de er ofte komplekse å sette opp, vanskelig å forstå og påvirker designet i for stor grad. Jeg ønsker å gi en enkel (teknologi og produktuavhengig) introduksjon til parallellisering, hvilke forutsetninger som må være på plass for at oppgaver gjøres i parallell, noen problemstillinger knyttet til å parallellisere, teknikkene master - worker, og map og reduce, og eksempler på en del typiske problemer som er egnet for parallellisering. Dersom du allerede jobber med storskala parallellisering er nok ikke dette presentasjonen for deg, dette er heller ikke en presentasjon av googles MapReduce rammeverk. Etter en introduksjonen til parallellisering vil jeg beskrive noen konkrete problemstillinger fra BBS hvor vi har hatt behov for å parallellisere jobber. Jeg kommer til å forklare hvorfor vi trengte å splitte opp og parallelisere jobbene, hvordan vi gjorde det, samt hva vi oppnådde rent konkret ytelsesmessig. Intro Noen teknikker for parallellisering Problemstillinger knyttet til parallellisering Eksempler fra BBS Oppsummering Q&A Language: Norwegian None Anyone interested in parallell processing/programming, but with little or none practical experience with it. Managing one-to-too-many relations in rich domain models Eirik Maus, developer, BBS Bjørn Bjerkeli, Senior Consultant, Zenior AS Lab 6, Torsdag kl. 14:15 Domain Driven Design with Object-Relational mapping is the state of the art for testable object oriented programming in domains with complex business rules. However, sometimes the domain contains natural relations and object graphs that are too large to fit in main memory. Even when you have sufficient memory, working with large object graphs that are naively OR-mapped can easily give you performance problems. Bjørn Bjerkeli and Eirik Maus present a few techniques they ve used at BBS to handle the one-to-too-many-relations (almost) without sacrificing working on a pure domain model. These include domain object fields based on database queries, iterators that page entities in and out of memory and simplified methods for background fragment processing. Problem description Relations and collections with Object-Relational Mapping libraries (Hibernate) Fix for running out of time : avoiding needless lazy-loading of large relation set for simple summation Fix for running out of memory: Paged Iterations / moving objects out of memory again Fix for running out of both time and memory: background fragment processing Things we haven t tried yet that we think might work Summary Duration: min Language: The talk can be given in english or norwegian. Slides in english Prior exposure to SQL databases and Object Relational mapping is recommended Developers and solution architects Creating attractive clients with NetBeans Rich Client Platform Mikael Tollefsen, Architect, Exie AS Lab 6, Torsdag kl. 17:00 Engineer tools like the familiar IDEs (Eclipse/IDEA/NetBeans etc.) have user interfaces increasingly different from office tools like Microsoft Office. When creating applications for end users it is important to aim for the look and feel this group is comfortable with rather than what would be intuitive for the engineer. At Exie AS we have developed an open source Swing look and feel component that dramatically simplifies this task. Just as it is important to utilize frameworks to improve productivity when developing web-based solution, so is the case with rich clients/desktop applications. A significant part of a desktop application consists of UI and IO plumbing. When should various menus, buttons and tool bars be enabled? Flexible docking frameworks, user preferences etc. There are various RCP frameworks available, however for a Swing based client the NetBeans RCP is perhaps the most complete. How to create an NetBeans RCP client and make it look like a member of the Microsoft Office package? It is quite easy, and I am going to show you how. Introduction The needs of an advanced rich client The main components of the NetBeans RCP The Office 2007 LAF OpenSource module (Demo) Creating a simple distributed, Internet enabled RCP from scratch Conclusions Q&A Side 32 Side 33

On the back of their large installed bases, vendor products were offered to customers to help them deploy and manage their attempts to develop Service Oriented Architectures, with the implication that Web Services were of little use without additional middleware to deal with their alleged inherent complexity. In this talk Jim will discuss how protocol-centric approaches like Web Services or the RESTful styles can constitute a robust integration fabric, providing the same benefits as proprietary middleware without vendor lock-in, and show how incremental, endpoint-centric integration is a viable strategy for enterprise service-oriented systems. Historical perspective of EAI Enterprise Architecture Today Deploying an ESB Enterprise architecture medium, long term Spaghetti Oriented Architecture Using commodity integration Web Services example Aiming for high cohesion with loose coupling Arriving at SOA Participants in this session should be aware of general SOA concepts such as services and buses. Architecture experience is useful, but not necessary. Architects and developers with an interest in SOA and enterprise architecture. No technical pre-requisites are necessary, but a sense of optimism, fun, and open-mindedness would be useful. Amazon EC2 Grid på Morten Udnæs, selvstendig konsulent i Udnæs Consulting Lab 2, Onsdag kl. 17:00 Thomas J. Watson (sjef for IBM ) skal ha sagt: I think there is a world market for maybe five computers. I tiår har folk ledd av dette utsagnet. Amazon lanserte i 2006 en løsning for Elastic Compute Cloud (EC2), dvs. virtuelle maskiner til leie. Fortsetter utviklingen med stadig mer bruk av EC2 er det ikke sikkert at Watson tok så feil Mange løsninger basert på moderne Java-arkitektur har behov for å lage skalere ytelse takt med at behovet vokser. Dersom man har et høy ytelseskrav (100 eller vis av transaksjoner pr. sekund) krever dette avansert og kostbar infrastruktur med mange servere og gjerne eget lagringsnett (SAN). Som Java utvikler gir dette en utfordring i forhold til hvordan man skal få utviklet og testet en slik applikasjon. Hvordan vet jeg at valgt arkitektur skalerer utover et par testservere? Hvordan vet jeg at løsningen skalerer i produksjonsmiljø over tid når volumene vokser? Dette foredraget gir et praktisk eksempel på hvordan man kan bruke Amazon EC2 som skalerbar infrastruktur for en Java Servlet basert applikasjon. Foredraget forutsetter ingen forkunnskap om EC2 og vil gi en kort introduksjon på hva EC2 er, hvordan det virker og hva man kan bruke det til. Dynamic languages and frameworks in an enterprise application server world - an approach with GlassFish v3 Alexis Moussine-Pouchkine, GlassFish evangelist Lab 3, Onsdag kl. 09:00 Dynamic languages and frameworks come in different shapes and forms but they all get attention from architects looking at providing application agility and better development speed while preserving the systemic qualities of more traditional runtimes (scalability, manageability, etc...) The first step is to have the dynamic language run on the JVM to benefit from the HotSpot investment, the second one is to have the associated web framework take advantage of an application server infrastructure providing pooling, recycling and other monitoring services. With the advent of modular architectures at the heart of modern application servers, it becomes now possible de make the wealth of Java APIs and the benefits of such a runtime available to artifacts beyond J2EE/Java EE. This talk will cover the value of dynamic languages to augment the value of existing applications and how these are implemented on the new, modular, OSGi-based GlassFish v3 architecture. It will discuss the integration of JRuby on Rails, PHP, Groovy/Grails, Python/Django and maybe other dynamic technologies in Glass- Fish. Demos and a couple success stories included. The list of APIs available to scripting frameworks include (but are not limited to): Metro (JAX-WS and advanced Web Services) Java Persistence API Grizzly Comet for Ajax Push JBI/ESB integration JMS/MQ connectivity Connector integration Audience: Java and scripting architects and developers. They will be able to see for themselves the value and the maturity of mixing a traditional application server approach with the agility provided by scripting languages and frameworks.

19 Enterprise application development and integration Enterprise application development and integration Taking Apache Camel for a Ride Bruce Snyder, Software consultant Lab 3, Onsdag kl. 17:00 The revered Enterprise Integration Patterns (EIP) book is indispensable for handling messaging-based integration, but utilizing these patterns in your own code can be tedious, especially if you have to write the code from scratch every time. Wouldn t it be nice if you had a simple API for these patterns that makes this easier? Enter Apache Camel, a message routing and mediation engine that provides a POJO-based implementation of the EIP patterns and a wonderfully simple Domain Specific Language (DSL) for expressing message routes. This session will introduce and demonstrate the power of Camel. So go on, take a Camel ride! Son of SOA: Resource Oriented Computing and Event Driven Architectures Eugene Ciurana, Director of Systems Infrastructure at LeapFrog Enterprises Lab 4, Onsdag kl. 11:45 Resource Oriented Computing systems process resource representations, execute transformations and computations by defining processing in terms of compositions and asynchronous sequences of resource requests. Application development and deployment using SOA faces problems when organizational changes occur if the participating systems (service providers and consumers) are too tightly coupled. In SOA, messages and systems are inherently synchronous, promoting dependencies that filter to the organizational level. Resource Oriented Computing solves system and application integration issues by leveraging ESB, domain-specific languages, and shared memory mechanisms for integrating coupling points, not the applications themselves, by promoting event-driven interactions between system components, and by creating logical mappings of resources such as data or computations that are abstracted from the physical manifestation of the system deployment. Who should attend Infrastructure architects Application architects Senior developers Application development managers Why do attendees need to be aware of this information today? Systems are built through the integration of decoupling points via ESBs, domain-specific languages, and shared memory mechanisms instead of direct integration of services, which is less flexible and more expensive in response to workflow or organizational changes Event-driven systems allow for shorter time-to-market application development and integration independently of organizational changes Treat computational resources as addressable entities (i.e. via object references, URIs, callbacks, etc.) that may be consu med on-demand rather than being intrinsically tied to specific applications Event-driven systems can be implemented by leveraging existing infrastructure and SOA investment Balance open-source vs. commercial products to avoid lock-in that results in higher costs and little or no flexibility during integration What basics should attendees know before attending this session? Enterprise service bus Basic understanding of distributed data caching technologies Enterprise integration patterns and SOA Event-driven distributed programming basics Java 5 or later Domain-specific language basics What problem(s)/challenge(s) will an attendee learn to solve by attending this session? How to develop complex applications within very tight deadlines by formalizing system integration around a resource-oriented model How to turn SOA-based systems into callbacks, breaking the rigid provider/consumer model How to develop event-driven applications based on technologies and services already in production using a multilanguage approach How to integrate the existing applications by applying eventdriven rather than centralized control techniques How to extend SOA beyond transactions to include workflow processes and lossless transformations of resources from one representation to another What else will attendees learn by attending this session? Real world applications that use Mule ESB, OpenSpaces, Terracotta and OSGi Examples of architecture, service objects, configuration files Approaches to solving distributed data caching Beyond the hype: OSGi in practice Costin Leau, SpringSource Senior Software Engineer Lab 4, Onsdag kl. 17:00 Modularity, versioning and dynamics make OSGi an ideal candidate for deploying and running Java applications, whether small or large. However, nothing comes for free and, like in any other environment, there are do s and don t s. In this session, we ll start by looking at OSGi (plus HK2 and JAM while we re at it) and then focus on some of the challenges that one might encounter when developing an enterprise application (containing web and data tier) in OSGi and how they can be addressed, using the lessons learned in Spring Dynamic Modules project and SpringSource Application Platform. OSGi overview Part 1: OSGi class and resource loading Persistence Part 2: Working with OSGi services Summary Q&A Basic OSGi, persistence and web knowledge Good Spring knowledge Good Java Class/Class Loading knowledge Anybody interested in using OSGi for enterprise applications Spring == XML, XML == sucks therefore Spring == sucks? Alef Arendsen Lab 4, Onsdag kl. 18:15 Last November, Spring 2.5 was released. This version of Spring, the de-facto Java EE application platform marks the beginning of the introduction of alternative ways to configure components. In the, we ve mainly focused on provided XML as the main language to perform Dependency Injection on object. Since 2.5, Spring has introduced several new ways to doing this. This session focuses on the various ways of using the Spring container to Dependency Inject objects such as the traditional XML language, the extensible namespaces, annotations, but also the innovative JavaConfig project that is capable of configuring Java objects annotations. Each has drawbacks and advantages and this session will discuss which one you should choose in what scenario. After this codeintensive session, you will walk away with a clear understanding of when XML is a good choice for configuration and when to opt for one of the annotation-based options. Short introduction of myself Short introduction of Dependency Injection as the general subject of the talk. There will be a lively, entertaining and mostly non-technical analogy for DI that will serve for thhe remainder of the talk XML configuration option Introduction, slides only Demos Drawbacks, advantages, hints, tips and configuration option Introduction slides only Demos Drawbacks, advantages, hints, tips and option Introduction slides only Demos Drawbacks, advantages, hints, tips and tricks Comparison to other frameworks / di approaches and conclusion The session is quite code intensive with relevant demos. Level: Anybody can join in, as it s entertaining even for those without Spring experience. For advanced users there s something to learn as well. Audience will leave with a clear understanding of Depedency Injection and the options Spring has to facilitate DI. RESTful Web Services with Spring Arjen Poutsma, senior consultant, SpringSource Lab 5, Onsdag kl. 11:45 REST, the REpresentational State Transfer, is the architectural style underlying the HTTP protocol. In the last couple of years, REST has emerged as a compelling and simpler alternative to SOAP/ WSDL/WS-*-based distributed architectures. In this session, Arjen will explain what REST is, how it can be used to build Web Services, and where it makes sense to use. We will look RESTful frameworks such as JSR-311, but focus on creating RESTful Web services with the Spring framework. This will include the features included in the current release of the Spring framework, and new features that are coming in the next major release. We will start by giving an overview of REST: where did it come from, how does it work, and how can it be used to build a distributed architecture? Using illustrative examples, we will try to find an answer to these questions. Next, we look at some of the current frameworks and tools which can be used to build web services. We will look at Spring-MVC and JSR-311 (also known as JAX-RS) on the server-side, and also investigate client- side options, such as the plain HttpURLConnection, and the more mature Commons HttpClient. Prerequisites: Spring framework knowledge EDR-MDS a less is more approach to SOA Master Data Management Thor Henning Hetland, Cheif Consultant, Objectware Lab 5, Onsdag kl. 17:00 Service Oriented Architecture is all over us. There seems to be some kind of consensus that one type of SOA services are services that are responsible for the core business objects - and vendors are monitoring and releasing their SOA Data Server products to close the gap. By pioneering the SOA space with EDR, we have gained lots of valuable of experiences of how to solve the Master Data challenges in SOA. This talk will discuss the main contenders for the ownership of your business objects definitions, and comment on their consequences - and then follow up with a Side 36 Side 37

The Enterprise without a Database John Davies, Serial entrepeneur - CTO of Incept5 Lab 1, Torsdag kl. 11:45 For decades, enterprise systems have been built around the database - the original canonical data structure that everything had to integrate to. The DBA was the most powerful person in the enterprise, even messages standards were based on the database structures and it seemed everything had to have a table associated with it. The time has come to think about an enterprise free from the RDBMS - not free from persistence altogether, but free from the lock-in of the classic RDBMS. John will talk through some recent projects at several large financial institutions now building global trading systems without a database in sight. Top 10 Patterns for Scaling Out Java Applications Cameron Purdy, Vice President of Development at Oracle Lab 1, Torsdag kl. 14:15 This presentation explores the challenges and solution patterns for managing data and compute tasks in scale-out environments. It is based on experiences with using a wide assortment of software solutions for compute and data management in scale-out environments, including newer scale-out technologies such as data grids and compute grids as well as getting the best results out of traditional database and messaging solutions. In the past two years I presented the talks The Top 10 Ways to Botch an Enterprise Java Technology-Based Application and The Top 10 Ways to Botch Enterprise Java Technology-Based Application Scalability and Reliability. Now that people have plenty of expertise on how to botch their applications, I wanted to shift focus from anti-patterns to patterns. The Top 10 theme remains as it keeps a quick pace and enforces a quick distillation of complex topics into simple concepts for the audience to remember. In this presentation I will use real world examples to demonstrate the challenges, solutions, and unexpected discoveries architects find when building scalable Java applications. I will site actual scenarios where each pattern has been used, and explain what the driving forces were behind these choices. (This talk consciously steers clear of discussing website scaling via content caching, as this is a topic well-covered by many whitepapers, presentations and other conferences. A few examples: For example, working on an ultra-low-latency JavaSpaces-based trading application was one of our first exposures to Recovery-Oriented Computing (ROC) for transaction processing in a production environment. The ROC concept can be used to achieve otherwise impossible results by selectively persisting only critical system state. Prior to this, we had generally steered clear of non-replicated in-memory data. But applying the ROC concept allowed us to achieve an order-of-magnitude latency improvement over what even the most efficient replicated-memory approach would have allowed, without compromising system availability. Likewise, working with a high-volume clearing application, a partner discovered that while serializable database isolation was required from a business perspective, and their database of choice enforced this optimistically, performing initial locking inmemory minimized the number of transaction rollbacks, substantially increasing system throughput. Much of this experience was acquired while working with customers in the usual early-adopter sectors: websites for retail, travel and hospitality; transaction processing and compute grids in investment banks; and more recently, the rush of so-called Web 2.0 startups. While in most of these cases, the primary reason for being onsite with the customer was the Coherence product that I am involved with, many of the more interesting lessons came from working with 3rd party products from dozens of vendors and open source communities, and learning alternate solutions to common problems from the people involved with those products. Some experience with enterprise application development Developers, IT Managers, Architects Real-world OpenESB, best practices and experiences Trond Strømme, Sun Microsystems Lab 2, Torsdag kl. 09:00 This talk will cover best practices for OpenESB usage and integration.

Extending Continuous Integration: Implementing a full value chain from development to production in Java EE Johannes Brodwall, lead software architect at BBS Lab 3, Torsdag kl. 10:15 Development is about more than writing code. It is even about more than writing tests! In order to produce something of value, we have to deliver reliable software into production. In an organization where the consequence of failure is great, we need to make sure that what we deliver works as intended. At the same time, even in a seemingly static world, many problems are hidden until the very end of the project. To make matters worse, complex technology and organizational processes inhibit our ability to act to new information with sufficient speed. The talk shows how we can implement a rigorous, yet agile process. It is based around our experiences of putting the good idea of continuous integration and other agile methods into life and using this as the basis not just for the technical process, but for the whole improvement program for our organization. We have expanded our process to cover simulated production as a part of the testing effort. This way, we can guarantee that the actual delivery day will be uneventful. The audience will come away from the talk with a good idea on how to improve their build process. The talk will cover both practical aspects, architectural changes that improves continuous integration, and what change you need to make in your organization to streamline the value chain from a code change to production readiness. The participants should have worked with Java in an enterprise context or had architectural responsibility for such a project. Architects and developers will come away from the session with an understanding of what part of the agile hype is real, what it requires to adopt, and how to get started. SOA Governance 5 common mistakes and how to avoid them Dan Diephouse, enterprise architect and open source developer Lab 3, Torsdag kl. 14:15 As the number of services and applications inside your organization grows, it becomes increasingly hard to manage and control. When this happens it is important to start looking at implementing SOA governance. Because SOA governance is not widely understood (or is widely misunderstood), many common mistakes arise which result in duplicate efforts, less reuse, less interoperability and increased development time. During this talk we ll look at what exactly SOA governance is while exploring 5 common mistakes and how to avoid them. What is Governance? What tools help you with governance? What are a registry/repository? 5 Common mistakes in SOA governance: Thinking governance is a product Not having a centralized source of truth Not enforcing architectural best practices Reinventing the wheel Inconsistent deployment strategies GridGain 2.0 Grid Computing Made Simple Nikita Ivanov Lab 4, Torsdag kl. 10:15 The topic of this presentation is about fastest growing open source Java grid computing framework called GridGain and how its focus on elegant simplicity and Enterprise Java integration is helping to revolutionize the grid computing for Java in the same way as Spring or JBoss have changed Enterprise Java landscape. The presentation will start with an introduction to grid computing and specifically data and compute grids. MapReduce will be discussed. Real-life examples will be discussed as well as common pitfalls, patterns and anti-patterns of using grid computing in real life. After introduction a comparison between GridGain and Hadoop (another popular MapReduce implementation) will be given with usual pros and cons of both projects. To underscore the topic of presentation it will also include live demonstration of writing a simple application and grid enabling it to run on a small grid right in front of the audience. All coding during demonstration will be done live. Detailed and in-depth explanations will highlight that grid computing in Java can be fun, simple and productive to use in everyday applications and systems. Introduction What is Grid Computing?
