It's not FacesServlet itself that needs to know ... it's the implementation of ViewHandler. The specification requirements for renderView() and restoreView() are defined in terms of understanding this, because it does things like map /foo.jsp to /foo.faces (if you are using extension mapping) or to /faces/foo.jsp (if you are using prefix mapping). > I didn't have a problem with the RI regarding validation of the web.xml. > I don't think the RI is even parsing the web.xml; it doesn't have a > context startup listener, unlike MyFaces. Actually, the RI *does* use a servlet context listener (com.sun.faces.confg.ConfigureListener). It's not required in web.xml because the RI lists this as a listener in the TLD for the tag library, which is embedded in the JAR file and therefore is implicitly registered. Looking at the RI implementation (it's available at java.net), the parse of web.xml has actually been pulled out (it was in the EA version for sure), and replaced by an algorithm that depends on null versus non-null values for servlet path and path info (ViewHandlerImpl.getMappingForRequest) -- that code looks like it might fail in some scenarios that I need to investigate further.
