don't use JSP, since facelets replaces it. and it comes nicely integrated with jsf2 in richfaces 4. why you need JSP?
thank for comment
Is there any way to use JSP with RF4? (a4j and rich taglib)
We are trying to migrate our application from JBoss 4.2.3 + JSF 1.2 + RF 3.3 to JBoss 5.1 + JSF 2 + RF 4, but a complete refactoring with facelets could be really hard.
