Which version of AS are you on? What you suggest is not be possible on AS 4.x since hibernate3.jar is in the lib/ folder, so the classes are loaded before server/xxx/deploy/jboss-aop.deployer is deployed. Unfortunately, even if you use compile-time weaving, you will still have problems since hibernate3.jar is deployed in a classloader that is the parent of loader containing the aop stuff. So basically on AS 4 you can only really aspectize the classes deployed as part of a deployment in the serve/xxx/deploy folder. I am not sure if anything else would work in AS 5 as it stands, but it could probably be made to work there.
