JavaOne2011

From APIDesign

JavaOne 2011 is around the corner, the question is what to talk about. Here are few thoughts:

Advanced Annotation Processing with JSR 269

Forget about runtime annotations as used for example by JavaEE or Spring. They don't worth a penny compared to advanced compiled time annotations processed by JavaC's AnnotationProcessors during compilation! Annotations of this kind change the way we think about Java. They can improve scalability, performance and simplicity of our Java frameworks without the hassle of on startup processing so common in the EE space these days.

Join us to learn how to design a Domain Specific Language in Java, how to improve the scalability of modular applications, how to improve startup time by building CompileTimeCaches, how to mimic the flexibility of Anything on Rails in plain Java, how to simplify your I18N practices! Learn from our rich, more than five years experience of building APIs around AnnotationProcessors. Learn how AnnotationProcessors simplify integration of your technology into any Java6 compliant IDE.

Join us to understand the power of modern Java!

Onward! Rebuilding IDEs around Shared Ground

There is just one IDE on the Java market that Oracle does not contribute to. Otherwise Oracle is involved in Eclipse Foundation, NetBeans.org project and of course its primary IDE for support of Oracle's enterprise technologies - JDeveloper. There has been a little component sharing between these three projects so far. This is fine when achieving other short term goals, but unsustainable as a long term strategy. Something has to be done about that.

NetBeans team is exploring the options of component sharability for few years. Join our talk to get a bit of overview of what we did and what we plan. Join us to see some cool demos showing bits of Eclipse running in NetBeans or JDeveloper and various other combinations of technologies. Join us to learn how to abstract, redesign, bridge and align projects that were diverging for years. Join us to understand the importance of common module system for Java.

Sharing can make our products better. Join us to share!

BOF: Experiences from Building the Fastest OSGi Container on the Planet

What is the fastest OSGi container? Felix or Equinox? None! The fastest OSGi container is Netbinox! But then, how do you measure how fast an OSGi container is anyway?

NetBeans project adopted OSGi in its 6.9 release. NetBeans platform applications can choose from running on top of Felix or Equinox. During work on version 7.0 we concentrated on optimizing the speed of startup, especially daily morning launch. This kind of start, when all OS caches are completely empty is very important for large desktop applications. By joining the the performance optimizations done to improve NetBeans IDE startup and Equinox we can start JDeveloper about 30% faster than plain Equinox could.

Hacking around OSGi container internals? Planning to embbed Felix or Equinox in your framework? Join us to learn how to do that effectively!
