I think he mentioned a while ago in this thread that the Flex needs the newer version for css related work.

I am with Carson. I would split the Flex portion of this into a different web app. BEA should suppport SSO across web-apps implicitly. The other option in my mind is to remove fop.jar from web-inf/flex/lib The rationale is that fop.jar would have been loaded by the web-apps loader. Since the server-side of Flex is honestly nothing but a couple of servlets and filters, the web-inf/lib loaded version of the jar would be cached in the loader already and loaded from there. >From your friendly neighborhood J2EE apologist..... -- Dave Wolf Cynergy Systems, Inc.
