pointcut $instanceof didn't work

[sharman]

Hi,

I have written a pointcut to intercept the Exception.

My jboss-aop.xml looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<aop>
 <aspect class="com.ac.detector.ExceptionHandlingAspect" scope="PER_INSTANCE"/>
 <bind pointcut="call(* $instanceof{java.lang.Exception}-&gt;*(..))">
 <advice aspect="com.ac.detector.ExceptionHandlingAspect" name="catchException"/>
 </bind>
</aop>

In my source file (which is a servlet), I have created an Exception object and calling a method on it...But it never gets intercepted. I am doing compile time weaving and then deploying it in jboss app server.

I even tried by trying pointcut="execution(* $instanceof{java.lang.Exception}->*(..))" ...but no luck....

Is this pointcut correct??? OR can some one give me some idea how can I define pointcut for method call on an Exception object????


Thanx

There should be no difference between Exceptions and normal classes, neither with regard to $instanceof{} nor call/execution usage

Thanx Kabir for the reply.

Yeah, I understand that there should be no difference between Exceptions and normal classes. But $instanceof{} somehow doesn't work on system class(like java.lang.Exception). It is working fine for me with normal classes. Can u please try this pointcut and see if the interceptor is called.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<aop>
 <aspect class="com.ac.detector.ExceptionHandlingAspect" scope="PER_INSTANCE"/>
 <bind pointcut="call(* $instanceof{java.lang.Exception}-&gt;*(..))">
 <advice aspect="com.ac.detector.ExceptionHandlingAspect" name="catchException"/>
 </bind>
</aop>

Thanx,

Create a minimal example showing everything, and I'll try to take a look
