hi, i misunderstood your question a bit, but if you test your subclasses on the inherited method you will see that they will be intercepted even though the subclass hasnt changed. For some transformation the subclass will also change, but not always. eg: <aop> | <interceptor name="MethodInt" class="MethodInterceptor" scope="PER_CLASS"/> | <bind pointcut="execution(public void $instanceof{POJO}->set*(java.lang.String))"> | <interceptor-ref name="MethodInt"/> | </bind> | </aop> public class POJO | { | private String text; | public void setText(String t) { text = t; } | } | public class SubPOJO extends POJO { | } in this case SubPOJO will not be changed by aopc, but MethodInsterceptor will still catch the SubPOJO.setText call.
