Otherwise you need to you need to make sure that jsf-facelets.jar is available to the classloader that is loading the tag - i.e. if jsf-facelets jar is in the war, the ComponentHandler should be as wel. Sorry - yeah - I've been spending WAY too much time behind the keyboard :-) I have the jsf-facelets.jar within the WEB-INF/lib/, and within the WEB-INF/classes, I should have had the com/test/ui/DisplayComponentHandler.class file. I didn't - which led to the error above. Thanks for the quick post. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4016105#...
