Eclipse Day Krakow 2012/Talks

Orion Tutorial

Szymon Brandys

Małgorzata Janczarska

git clone slides
git clone examples

Orion is an open tool integration platform for writing browser-based development tools. In this tutorial you will learn how to use the Orion platform and extend it by integrating other web pages and services into the Orion development workflow. Close integration is achieved through writing Orion plugins to extend the platform with additional capabilities. We will walk through the process from a simple first plugin, up to a plugin that extends Orion in a variety of way: adding links to other pages, new language tools, and even a brief foray into connecting Orion with remote file systems.

Redefining Modularity with Object Teams

Stephan Herrmann


Modularity is our key concept for mastering complexity, but what kind of modularity do we need to address the challenges of tomorrow? Can a programming language provide the necessary means? Can Java?

The Object Teams approach demonstrates how far a truly object-oriented programming language can go, how classes and objects can indeed be the building blocks for uncompromisingly modular software designs. Rather than introducing new kinds of modules the approach adds new ways how classes and objects can be connected into a system: Existing relationships like nesting and inheritance are enhanced and only one new relationship is introduced: role playing.

With these conceptual tools every requirement, every reusable asset can be cast into a module. Every variation of an existing system can be described by an additional module. Object Teams supports modularity in all circumstances: extreme modularity.

For more than 5 years OT/J has been successfully used in plug-in development, including, e.g., a prototype for JDT's new annotation-based null analysis as a separately deployable module.

Extracted from such applications this presentation will show the most useful patterns, patterns that don't trade one solution for a bag of new problems but holistically improve software quality.

In this presentation the audience will see little syntax of OT/J, that's not where big things happen, but the goal is to change the way developers think about modularity.

No more excuse for your NPE: JDT 3.8 understands null-annotations

Stephan Herrmann

NullPointerExceptions are among the most common and most embarrassing symptoms of failures in Java programs. Starting with the Juno release, JDT has entered the next stage of fighting NPE as-you-type: annotating your code with null specifications. This talk will show you how to get the most from this new feature, and I will outline what's currently cooking.

Tworzenie aplikacji typu Rich Clients za pomocą Eclipse 4 RCP

Kamil Piętak


Language: Polish

The recently released Eclipse 4 RCP delivers brand new features that significantly improve building rich client applications. Application model, dependency injection, built-in services are the more important elements that allow to easily create brand new applications (not only IDEs).

In the talk I will shortly present the most important features of Eclipse 4 RCP in contrast of the ones that exist in the 3.x branch.

Eclipse Command Language

Bartosz Czerwiński


Eclipse Command Language is a Domain Specific Language for Eclipse-based applications, which simply enables advanced scripting and automation. It was initially introduced by Xored at EclipseCon in 2008 and it follows projects such as Eclipse Monkey and Glimmer. One of the main aims of ECL was to support scripting in Q7 functional testing tool. Presently, ECL as an independent open-source project is a complete Scripting and Automation solution for Eclipse framework.

This talk will cover basics of ECL, its architecture, usage examples, and its future.

Eclipse of idleness and focus on current task

Dariusz Łuksza


Did you ever wonder how you can improve your productivity and accomplish more in less time ? Do you know how to reduce context switches to improve yours focus ? What Eclipse plugins can help you increase productivity ? This presentation will answer for all those questions and more. It will be about Mylyn project and other Eclipse productivity plugins; about (less or more know) keyboard shortcuts and how to avoid disruptions from other team members, etc.

Dekonstrukcja architektury w czasach kryzysu

Jarosław Pałka

Language: Polish

Napięte terminy, budżety na ścisłej diecie, eksplodujące metryki KLOC,CC,RFC, mgławice technologii, paradygmatów oraz manifestów. Rozproszone zespoły, "nonsensownie" wielkie i złożone systemy. Czy w dobie globalnego kryzysu finansowego, jesteśmy też świadkami (a być może też sprawcami) kryzysu w naszej branży? Kryzysu, który ma o wiele dalej wybiegające konsekwencje.

Podczas prezentacji spróbujemy zrozumieć czym jest kryzys architektury systemów IT, jakie są jego źródła i konsekwencje. Spróbujemy też wyjrzeć poza nasz "ogródek", i poszukać rozwiązań korzystając z "myślenia systemowego" i "teorii systemów złożonych". Przyglądniemy się archetypom systemów, zrozumiemy czym charakteryzują się "złożone systemy" i jakie rozwiązania proponują prezentowane podejścia. Czy zamiast analizować kolejne linijki kodu, próbując zrozumieć intencje autora, możemy usprawnić nasz system, niekoniecznie paraliżując nasz system nerwowy. Czy znajomość własności hierarchii systemów, źródeł tzw. "emerging behaviours" pozwoli nam uniknąć problemów w przyszłości. Czy może zamiast poznawać kolejne języki programowania, paradygmaty które z czasem przeminą lub okażą się niekompletne nie powinniśmy zainwestować naszego czasu w zgłębienie natury rzeczy? Natury "systemów" i ich "złożoności.

Tycho - using maven to build OSGi plugins

Krzysztof Daniel

Building OSGi applications was always a pain. Various approaches did not work well due to specific dependency handling, conflicts, and similar issues. Only recent Eclipse project called Tycho seems to use both maven for the simplicity and Equinox for dependency management making builds really easy. This talk will give insights into how Tycho is built and how it works.

XText - creating your own code generation tools

Krzysztof Daniel

Domain Specific Languages provide a real benefit to many non-IT specialist, which can learn very quickly how to program things they really now without knowing how to program. In this talk I would like to present slightly different scenario - writing a code generator for IT purposes, which will make us free from certain tasks that require a lot of copy-pasting.

Commercial use of Eclipse with IBM Netezza Plug-in

Agata Hejmej

The EPL license makes the Eclipse open source a valuable basis for commercial offerings. In the presentation I will talk about developing a dedicated Eclipse-based IDE - IBM Netezza Plug-in for Eclipse Framework, and share tips in creating a commercial Eclipse-based product.

The OHF Legacy


Werner Keil

After an looking back at the history of Eclipse OHF and its parts, we're going to learn what happened to them and why.
Beside those going a different path, mainly Open Health Tools (OHT) we take a closer look at the Legacy of OHF at Eclipse, mainly The Spatiotemporal Epidemiological Modeler (STEM) and Units of Measurement support from UOMo and related standards like the Unified Code for Units of Measure (UCUM)

The MAT Tutorial

News from Git in Java Land

Stefan Lay


Curious what's new in the Java Git ecosystem? Want to know more about the state of Git in the ALM space?

We'll demo some of the new features of JGit and EGit 2.0 shipped together with the Juno Eclipse release. We'll also show some new stuff coming with the next Gerrit code review release, its Eclipse integration shipping with Mylyn Reviews and what improvements were made around workflows using the GitHub Mylyn connector.


Paweł Pogorzelski

Wondering what's going on in the OSGi community? Or simply not satisfied with current modularity level OSGi provides? Well, OSGi Alliance addresses this concern with OSGi Enterprise Release 5, driven by "applications in OSGi" theme. Come and hear about enhancements in one of the simplest, yet one of the most powerful Java runtimes available.

Portal to Rich Client Platform - migration of mission critical application

Radosław Urbaś

Migration of an application and its users from one platform to another is not an easy task. During the talk I will present how we build our Eclipse RCP application at Sabre and how we migrated 400k users from legacy portal based system into a new environment. I will talk about our E2E development process and how we plan to expand our platform.

Foundations 2.0

Mike Milinkovich


Open source foundations such as GNU, Apache and Eclipse have been with us now for about twenty years. For that time period, their role has been fairly consistent: they provide a neutral place for developers to create and distribute free software. This model has served both the open source community and the industry well. However, two forces are forcing a re-thinking of the role and function of open source foundations. The first is the huge success of project hosting sites, particularly github. The second is the mainstream success of open source. Drawing from my experiences at the Eclipse Foundation, I will be discussing the innovations in governance and programs that will keep open source foundations at the forefront of the software industry for many years to come.
