I've noticed that the web.xml files included with the JSF sample (samples/netui-jsf) include filter-mapping for both .faces and .jsf but a servlet-mapping for .faces only.
At first I thought there was a code problem but with the .jsf servlet-mapping either extension works. I also noticed that both the .faces and .jsf filter-mapping are in the web.xml file included in samples/netui-samples but neither JSF servlet-mapping. - john
