Hello, Although I'm not attempting to use SEAM (just JSF) this page seems the closest match to what I'm experiencing. I'm using jboss4.0.4.GA, default JSF, and attempting to deploy a war with Sun rave UI in it, from Java Studio Creator 2. Just like you mentioned, the sun ui components don't render at all, but I don't get any exceptions either. o I'm including sun's jars in the ear containing the war (except sun jsf jars) o I copied Sun's jstl.jar and default.jar to deploy/jbossweb-tomcat55.sar. o I added in the creator.taglib.xml as you explained, and context-param in web.xml Still the same thing, no errors, nothing rendered. Do you have any suggestion? Thanks, -Aron View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984348#...
