Hi there!

I came to that problem tonight again..

Actually, it does make sense. One can has 
"execution(* class->method(..)) AND !within(ExcludedClass)" in AspectJ.

It makes sense. I'd like to intercept any execution of method "method", but not in the class "ExcludedClass". How would that be with JBAOP?

Hi Tomasz,

"within" only works with call, i.e "instrument the caller of xxx only if we are making the call from within yyy".

In the case of "normal"/execution of instumentation we do not care (or have any info about) who is calling the target. AspectJ's weaving works differently. To achieve what you want with JBoss AOP you wuld currently have to use cflow.

Cheers,

Kabir

Hi there!

Yes, as a workaround I've used cflow.

AspectJ weaves in different way, but the semantic stays the same.

Isn't there really any info about a method's class?
'within' takes class expression as an argument, right?

If you have access to a method, then you should also have access to the method's class. You weave the method itself, so you have access to the method's class. I don't know the details but it seems possible.

Comment..?

PS. I cannot use "call" because calls are made by Struts framework. Let's assume I log '* Action->execute(..)'.
