I don't know what exactly was happening in your environment. However I like to shed some light on your issue. Basically there is a listener in myfaces_core.tld in myfaces-impl.jar: <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class> This listener should be automatically registered before your FacesServlet was initialized. The work of the listener is to do lots of configurations such as parse faces-config.xml. It seems the listenered was not registed in your web context where your FacesServlet could was running.
