Hi Guna,
have you solved this problem? I'm experiencing exactly the same issue. If I place the *.aop file inside an EAR with the precompiled classes the aspects do not get called. However, if I take the same AOP File and place it side-by-side with the EAR (and remove the AOP from the application.xml file) the aspects get called.
Any hint is very much appeciated
