RichFaces is an open source, advanced user interface component framework which is used to easily integrate Ajax capabilities into JavaServer application.
It is designed and developed by Jboss. It is implemented as a component library which adds Ajax capability into existing pages. So, a developer doesn't need to write any JavaScript or JQuery code.
RichFaces uses several parts of the JSF 2 framework including the lifecycle, validation, conversion facilities and management of resources.
RichFaces 4 supports full JSF 2 integration and uses standard web application technologies such as JavaScript, XML (Extensible Markup Language), and XHTML (Extensible Hypertext Markup Language).
