I tried that and it showed that the project was already configured. So I removed it from the configured list and clicked finish. Then I tried DebugAs->Debug on Server again and it worked! I had originally deployed using RunAs->Run on Server and I could not find a way to undeploy from the IDE, so I "used the bigger hammer" and just deleted the EAR from the Jboss deploy directory. The JBoss console showed a successful undeploy, but I wonder if the IDE didn't recognize that it had happened?
