It would be a very good documentation hint if you add all needed libs and its versions for JBoss Tools and JBoss Portal. I would help you here but iam a real newbie to JBoss and its tools. Then i found a little bug, sometimes when undeploying a project it is not deleted in the jboss workspace directory .metadata\.plugins\org.jboss.ide.eclipse.as.core\JBoss_Application_Server_4.2_-_jboss-portal-2.7.1\deploy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203994#...
