It's all by the spec. ;-) What you had before was actually 3 deployments as directories that don't have a '.' in the name are not treated as top level deployments. Hence when you tried to lookup a resource from one of them, probably the other one wasn't "ready" yet. If you have a '.' in your "grouping" directory, it will be treated as a top level deployment, having those 2 files as sub-deployments and a metadata file. This should of course see its resources at any given post-cl-creation time. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4232453#...
