Can you tell me how to find out which version of Richfaces I am running?
I need to know if I have jQuery already installed so perhaps a way to test that would help as an answer as well.
I am using Version: 2.1.0.GA of JBOSS Developer Studio.. if that helps.

In JBoss developer studio (which is based on Eclipse), right-click your project and choose
Build Path > Configure Build Path
There you have the Libraries tab, where all libraries are listed. Look for richfaces and see the version.
Another way - when you deploy your application, check the WEB-INF/lib folder. There should be the richfaces jar there, with version included.
