    The right URL is:http://host/path/page.jsf If I access the jsf page URL by mistake like: http://host/path/page1.jsf It changed the jsf extension to JSP by itself, and then triggered 500 error. The log says: SEVERE: PWC6117: File "/path/page1.jsp" not found WARNING: StandardWrapperValve[Faces Servlet]: PWC1406: Servlet.service() for servlet Faces Servlet threw exception
