I've done this change. It will need a jboss-deployers release to make it work. See the JIRA issue for how this works. It's a bit ugly though if you want to add your subdeployment classloader to the default domain since you've got to specify something like: | <classloading domain="DefaultDomain" parentDomain="DefaultDomain"/> | But if you're doing that I don't see why you would need a subdeployment classloader anyway ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154352#...
