[jboss-user] [JBoss AOP] - Intercepting EJB3 EntityBeans
I am trying to intercept EJB3 EntityBean methods, but I'm getting a
javassist.CannotCompileException.
The jboss-aop.xml file I'm using is:
<aop>
| <typedef
| name="logclasses"
| expr="class(test.*) AND
| !class(test.aop.*)"/>
| <bind pointcut="execution(* $typedef{logclasses}->*(..))">
| <interceptor
| class="aop.LoggingInterceptor"/>
| </bind>
| </aop>
And the exception I get is:

etc...
The weird thing is that the pointcut is properly bound to non-EntityBeans in the same
package. How can I get the pointcut to bind to EntityBeans too?
