Given that the aop file of module-one.ear is affecting module-two.ear and vice-versa, you just need this aop file in one of the modules. I would choose the .ear file that is in the deploy directory. AFAIK, putting the .aop file directly in the deploy dir should also work. This way, your packaging structure would be cleaner, since the .aop file affects not only module-one.ear, but also module-two.ear. Let me know if this works. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077002#...
