I set an AllPermission policy tried it as well VM Parameter and also in the code(see client.policy). Could this be due to the ClassLoader redesign? Tried it on JBoss 5 Beta 3 too without luck. So something must have happened between 4.0.X --> 4.2 | grant { | permission java.security.AllPermission; | }; | (Yes I know not very secure) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117544#...
