Can you briefly explain how struts even works when loaded from a shared ClassLoader? My reading of this suggests that shared struts would not be able to load actions found in the webapp's ClassLoader(s), but it sounds like the OP has done this successfully. I'm just curious how it is done because you say above that this is a naive implementation... how does one do this in a smart way? It's not too relevant to the question... just thought I'd take the opportunity to find out since I've never heard of a good way to search "down" the ClassLoader hierarchy.
