Open JavaServer Faces
In its continuing open-source effort, Sun has made the source code of its implementation of JavaServer Faces available under the
OSI approved Common Development and Distribution License (CDDL). More information about that license can be found here.
JavaServer Faces has had external contributions, and this open-source strategy will make it easier to get contributions into the technology. The news comes just as JavaServer Faces is ramping up for the start of its 2.0 release - a release that promises exciting new features.
So, you are certainly encouraged to get involved. Want to get involved? You can start here.
