JSF & RichFaces

JSF : java server faces
myfaces : apache component library that is based on jsf
richfaces : jboss component library m which also based on jsf
http://livedemo.exadel.com/richfaces-demo/richfaces/form.jsf?c=form
(very good livedemo for all the richfaces components )

JSF : set up environment

1- you need first to add the jsf libraries (jsf-api.jar, jsf-impl.jar, jsf-facelets.jar),
most of the IDEs support this Jars if u choose faces project

2-if u are going to use richfaces so you need to add the richfaces jars
(richfaces-api-3.1.0.jar,richfaces-impl-3.1.0.jar,richfaces-ui-3.1.0.jar) and use the tag
libarary (<%@taglib uri="http://richfaces.org/rich" prefix="rich"%>).

3-you have to add the jstl.jar and standard.jar and some commons jars

note: if u add richfaces jars, don`t add ajax4jsf because the same classes are in richfaces.

To DownLoad richfaces jars :
