ICEfaces is an open-source Rich Internet Application (RIA) development framework based on the JavaServer Faces (JSF) 2 standard. Like its predecessor, ICEfaces 1.8, ICEfaces 2+ extends JSF to simplify development and enhance the standard JSF feature set - simultaneously improving developer efficiency and expanding the spectrum of RIA capabilities that can be included in any JSF-based web application.

Adhering closely to the standard JSF 2 extension points allows ICEfaces to work transparently with the stock JSF framework, simplifying integration and fostering 3rd party compatibility with other JSF 2-compliant libraries.
