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 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.

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."

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].

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.
