Well, I haven't actually deployed a JSF on WAS 5.0. I mostly work with 5.1. You should probably focus on why the application isn't working. Are you missing a class? It could be that WAS can't find the JSF classes. If it's one of the java or javax packages causing the problem, then you may be right about it being a lack of WAS support.
