RichFaces

The next-generation JSF component framework by JBoss!

The RichFaces project is an advanced UI component framework for easily integrating Ajax capabilities into business applications using JSF.  

RichFaces 4 builds upon the pioneering Ajax support that began with RichFaces 3 and is standardized in JSF 2. In addition to extending these ajax capabilities, RichFaces also improves other areas of JSF 2, including usability, performance tuning, dynamic resources, skinning, and component development.  This allows users to take full advantage of all the productivity enhancements of JSF 2.
