State Chart XML (SCXML) is currently a Working Draft published by the World Wide Web Consortium (W3C). SCXML provides a generic state-machine based execution environment based on Harel State Tables. SCXML is a candidate for the control language within multiple markup languages coming out of the W3C (see Working Draft for details). Commons SCXML is an implementation aimed at creating and maintaining a Java SCXML engine capable of executing a state machine defined using a SCXML document, while abstracting out the environment interfaces.
Qwicket is a quickstart application for the wicket framework. Its intent is to provide a rapid method for creating a new wicket project with the basic infrastructure in place so that you can quickly get to the meat of your application rather than mucking with the plumbing of a wicket application. Currently, the system only supports spring and hibernate built with ant. Future plans include support for maven 2 and other persistence layers such as ibatis.
Felix is a community effort to implement the OSGi R4 Service Platform, which includes the OSGi framework and standard services, as well as providing and supporting other interesting OSGi-related technologies.

You can hardly turn a web page these days without seeing a story that describes how people are using social networks, whether it is Twitter, Facebook or some other service to develop and build their personal communities.
When solving problems, how useful might it be if a user was able to tap into the collective knowledge of her peers or surrounding groups of people with whom she might naturally network in the workplace setting? How much quicker and with greater precision might she be able to solve daily problems? What if there was a communications mechanism that takes the best of what services like Twitter offers and co-mingled that with readily recognizable business processes? That solution is Apache ESME.
