You can deploy not-exploded ear and edit jsp in tmp/deploy/xxx directory. I was using this solution. Sometimes there is problem with refresh changes but I think it requires some touching on specific files. And problem is to synchronize it over cluster - Maybe you will have to hand copy changes to other cluster nodes. Or If you using cluster maybe you can sequentially execute steps: stop-start cluster node with updated ear - and all time you application is available. I don't know how JBoss support that solution.
