The standalone one seems to get the correct AOP stack to create connections, but the client running inside jboss does not. Could it possibly be loading from the wrong file? I think it will be something else (not related to AOP), but It's impossible to tell without more information. (Stack traces.. logs.. etc.) You will have to investigate, and ping us with more information if you can't figure out. Probably there's a classpath issue at one of your clients.
