hi, some more information of what you want to do would be appreciated. but a rule of thumb is that you cant use aop on ejbclasses since these are not the "same" classes you write and deploy in the appserver. the appserver adds a lot of "magic" to your ejbbeans when they are deployed. will the interceptor mechanism in the ejb3 spec fulfill your needs?
