[JBoss-user] [EJB 3.0] - Re: Interceptors not fired on methods called from within bea

By calling the method via a bean reference, the server has a chance to determine that an interceptor exists and can deflect the method call to the interceptor.  But, within the bean, if you call another method dicrectly, that all gets compiled into the class file and the server does not have any chance to intercept the method call.

Interesting.  I was under the impression that is was implemented via byte code instrumentation by the underlying provider in the classloader, in the case of JBossAS, jboss-aop.  Thus, there should be no real technical restrictions on when the method can be intercepted.  The spec may have additional restrictions though.

Is this bean reference restriction stuff mentioned in the spec?  I didn't see anything like this under the Interceptors section.

Thanks for the reply.
