From now through Friday, February 16, you can ask your questions about the Java Plug-In and have them answered by Java SE Deployment Team members Dennis Gu, Calvin Cheung, and Margarita Fisher.
The JSR-296 Swing Application Framework prototype implementation is a small set of Java classes that simplify building desktop applications. The prototype provides infrastructure that's common to most desktop applications: application lifecyle, support for managing and loading resources, support for defining/managing/binding Actions, and persistent session state. The JSR-296 expert group launched this effort in late summer 2006. A prototype implementation, spec, and some small examples are now available. Although the JSR has not reached the "Early Draft" JCP review stage, the expert group has agreed to make the prototype public to give interested members of the Swing community the opportunity to provide feedback. This version is just a snapshot of the ongoing design process, it's likely to change substantially in the coming months.
The registration page for the JavaOne 2007 conference is now available. Early Bird discounts apply to conference passes purchased before April 4.

The 3D desktop Project Looking Glass is approaching its 1.0 release, with the recent announcement of LG3D 1.0 RC1, with a final release expected soon. But what is a "3D" desktop? According to its home page, "Project Looking Glass is based on Java technology and explores bringing a richer user experience to the desktop and applications via 3D windowing and visualization capabilities. It is an open source development project based on and evolved from Sun Microsystems' Advanced Development division. It supports running unmodified existing applications in a 3D space, as well as APIs for 3D window manager and application development."
The Semblance project provides reusable components for Java applications in the form of two framework subprojects and an example application subproject. Semblance emerged from earlier work done in the StrutsLive framework, as it came to include a number of powerful and generically useful facilities that could potentially add a great deal of value outside the web tier. The Semblance project made it possible to divide the original StrutsLive codebase into two frameworks. Struts-dependent code would remain in StrutsLive, and the rest would move to the new Foundation framework, no longer encumbered by ties to Struts, or to the web tier in general.
The Mobile & Embedded Community is a gathering place that enables and empowers developers to collaborate and innovate, driving the evolution and adoption of the Java(TM) Platform, Micro Edition (Java ME) for mobile and embedded devices. Here you can be a part of a robust culture of developers and technology experts and find people with similar interests and goals. For more information, see our community vision.
The Semblance project has announced the release of Semblance 1.0B1, which incorporates the StrutsLive framework (formerly maintained as a separate project) a new Foundation framework, and a comprehensive example application. This is a major feature release that adds support for XHTML templating, dynamic query generation, and list management, including pagination, navigation, sorting, filtering, and selection management. Please see the release notes for further details.
Want JSF without JSP? Have a look at Facelets. "The web community is eagerly seeking a framework like Tapestry, backed by JavaServer Faces as the industry standard. While JavaServer Faces and JSP are meant to be aligned, Facelets steps outside of the JSP spec and provides a highly performant, JSF-centric view technology. Anyone who has created a JSP page will be able to do the same with Facelets. The difference is under the hood where all the burden of the JSP Vendor API is removed to more greatly enhance JSF performance and provide easy plug-and-go development."

Post your questions and you'll get answers from key members of Sun's Swing, Java2D, and AWT teams, namely Scott Violet (Swing Architect), Shannon Hickey (Swing Technical Lead), Chris Campbell (Java 2D Engineer), and Oleg Sukhodolsky (AWT Technical Lead). This Ask the Experts session runs from Monday, October 16 through Friday, October 20.
The TrueLicense Library Collection "aims at managing licensing aspects for closed source Java applications in a secure, reliable, flexible and yet easy way." The package allows you to create and verify licenses that are bound to a person, company, or any other entity, can be perpetual or granted for a specific time, and can provide a "free trial period" license functionality. Licenses use the digital signature methods of the Java Security API, and privacy of installed license content is maintained by using the password based encryption mechanisms provided by the Java Cryptography Extension. The project also offers two tutorials, the The TrueLicense Library Collection Tutorial and the Introduction to the TrueLicense Library Collection[PDF].
The Timing Framework project is a library to simplify Java animation and timing-based control. Introduced by the articles Timing is Everything and Time Again, it offers fundamental timing classes, interpolation facilities, and a set of trigger classes to facilitate starting and stopping animation based on events.
Need continuous integration? Check out Hudson. This project monitors executions of repeated jobs, such as software builds or automated tests. "Hudson provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continoues build increases the productivity." Features include easy installation, change sets, permalinks to "latest build" and "latest successful build", RSS/e-mail integration, distributed builds, plugin support, and more
Developing JNI code isn't the easiest task, but GlueGen makes it somwahat easier to manage. The project page describes GlueGen as "a tool which automatically generates the Java and JNI code necessary to call C libraries. It reads as input ANSI C header files and separate configuration files which provide control over many aspects of the glue code generation. GlueGen uses a complete ANSI C parser and an internal representation (IR) capable of representing all C types to represent the APIs for which it generates interfaces." GlueGen is used to generate several Java-to-C wrapper libraries, including JOGL and JOAL.
Subversion is one of your choices for version control when starting a java.net project, and now CollabNet, which powers the project hosting and collaboration facilities on java.net, has posed a one-hour webinar on Subversion Best Practices, hosted by CollabNet's Chris Clarke and Garrett Rooney.
