That is a generic java error message. It means you've compiled with one jdk and are trying to run with a JRE of a different (lower) version.
Specifically, your workspace compiler is probably java 6, and you're running jboss with a 5.0 JRE. (That's my best guess) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140988#4140988 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4140988 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
