I’m trying to use RichFaces on a working JSF2 application. I incorporated the RichFaces jars, changed the web.xml but got the following error:
17:49:13,097 SEVERE [javax.enterprise.resource.webcontainer.jsf.application] Error Rendering View[/login.xhtml]: java.lang.NullPointerExcept

It seems that some jars are missing, but I cannot seem to find this cause. The above error is the only thing that the log spits out.
