I already removed the tag but it does not make any different. Are you using the same version 2.6 as well? I read something off from sourceforge for JBoss bug [JBPORTAL-1246] Error while creating javascript includes using jboss-portlet.xml I dont' know if this is true or not, but even if I include a css file as said in JBoss portal document, there is no such line show up in the main portal. By the way, the url for my portal is http://localhost:8080/portal Any ideas? thanks, TL View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4070287#...
