I thought that would be analogous to what David is trying to do?

This sounds more like a configuration (i.e. metadata overrides, i.e. profile service issue) than a deployment shaped one. David, if you've got the time, have you got an example of the original service deployment descriptor and an example change you would expect to see. This might help clarify if the profile service would help here or not. Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4191893#...
