The UISpec4j project offers a functional/unit testing library for Swing-based applications. "UISpec4J was conceived in an Extreme Programming environment, where automated testing takes a central place. The existing Swing-based testing frameworks did expose too much of the Swing APIs, resulting in arcane and unmaintainable test classes. This is why we decided to implement a set of wrappers, trying to make our tests as close as possible to human-readable text.
Our ultimate goal is to allow tests written with UISpec4J to become the actual detailed specification of an application."
Java Native Access (JNA) provides Java programs easy access to native shared libraries (DLLs on Windows) without writing anything but Java code--no JNI or native code is required. This functionality is comparable to Windows' Platform/Invoke and Python's ctypes. Access is dynamic at runtime without code generation. JNA's design aims to provide native access in a natural way with a minimum of effort. No boilerplate or generated code is required. While some attention is paid to performance, correctness and ease of use take priority.
This week's Ask the Experts session is on Java SE 6 Update 10. "Java SE 6 Update 10, currently available as a beta release, introduces many new features and enhancements that dramatically improve the developer and user experience. Some of the significant improvements in Java SE 6 result in faster and easier deployment of Java applications and applets, better performance, and an improved look and feel. Got a question about Java SE 6 Update 10? Post it during this session and get answers from three key members of Sun's Java SE Platform team: Danny Coward, Ken Russell, and Richard Bair."
BTrace is a safe, dynamic tracing tool for the Java platform. BTrace can be used to dynamically trace a running
Java program (similar to DTrace for OpenSolaris applications and OS). BTrace dynamically instruments the classes of the target application to inject tracing code
("bytecode tracing"). Tracing code is expressed in Java programming language. There is also integration with
DTrace for the OpenSolaris platform. There will be a VisualVM plugin
for BTrace soon - so that the users can trace their application from the VisualVM client. Alternatively, if you'd prefer you can run BTrace from command line shells as well. BTrace is available under GNU Public License v.2 w/Classpath Exception.
One of the most talked-about introductions at JavaOne 2008, the Lightweight UI Toolkit (LWUIT) makes it very easy to create compelling UI's that will look and behave the same on all devices using a programming paradigm similar to Swing. It supports platform look-and-feels and themes, touch screen functionality, animation and transitions, rich widgets, 3D integration, painters, and more. The project already has a wealth of information available, including a tutorial, developer's guide (PDF), javadocs, and a wiki. You can also learn more in episode 46 of the Java Mobility Podcast.
Part of both the JavaFX and SwingLabs communities, Project Scene Graph provides the scene graph -- a hierarchical representation of objects in a scene -- called for by JavaFX Script, allowing for its use by general Swing applications as well. The project's latest release is version 0.6, which adds some APIs, fixes bugs, and adds a number of new visual effects.
The Da Vinci Machine Project is "extending the JVM with first-class architectural support for languages other than Java, especially dynamic languages. This project will prototype a number of extensions to the JVM, so that it can run non-Java languages efficiently, with a performance level comparable to that of Java itself." The group is hosting a JVM Language Summit on the Sun Microsystem Santa Clara campus, September 24-26, an "open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects."
One of the significant new features added to NetBeans IDE 6 is support for JRuby.

The overall goal of Project Open JBI Components is to foster community-based development of JBI components that conform to the Java Business Integration specification (JSR 208). You can join this project as a JBI component developer or as part of an existing JBI component development team. Starting your own component project is relatively straightforward: you have the option to create your JBI component project as a regular Java.Net project. Joining an established development team might take a little longer and require additional approvals.
The Kijaro project "provides an area for those interested in adding new language features to Java to try out their ideas." Starting from a copy of the OpenJDK
javac compiler, the project has gone off on several interesting branches, including the First Class Methods implementation, properties, abstract enums, static implements/contracts, anonymous parameters, and list comprehensions. The project describes itself as "similar to KSL", but without the legal overhead.
As announced in a recent press release, the non-profit industry consortium CableLabs has launched the OpenCable Project on java.net. The OpenCable Platform is a Java-based middleware software layer that "provides the opportunity for operators to deliver interactive services and applications to consumers bundled with their other service offerings. Content Programmers may also leverage the OpenCable Platform to enhance their own programming and advertising offerings and perhaps evolve new businesses around these new services."
The OpenJDK JDK 6 project, a backport of the evolving GPL+CPE codebase to the JDK 6 spec, has posted its first source release. Due to IP encumbrances, some classes are not available as source, and are instead provided as "binary plugs" for Windows, Solaris (32- and 64-bit) and Linux (i586 and AMD64). More details about the project are available in Joe Darcy's blog and his initial project proposal. Those interested in the OpenJDK project will also want to check out the OpenJDK Developers' Guide, an early attempt to document everything needed by would-be contributors, from checking out code to contributing patches.
