[ajdt-dev] Advice, raising different exceptions depending on 'pointcut'

["Marco Mistroni" <mmistroni@xxxxxxxxx>]

Hello all,
  i have  following usecase..
I need to intercept all calls to   the method setOwner for all ejbs in package com.myapp.ejbs.
If the owner does not satisfy a certain condition, i need to raise an exception.
the challenge here is that the exception type to be raised must be the same exception that
the intercepted pointcut is catching.
Now, i posted some time ago here about raising exception from aspects, and after that i have
created a ConcernRuntimeException to be raised if my advice raises some exceptions.
THis exception wraps the original exception so that the calling object will be able to handle the exception properly.

But in this case, my pointcut will intercept methods of different EJBs, which raise potentially
different exceptions..
I have some constraints for NOT to change so that all ejbs intercepted methods raise exactly the same
exception.

I was wondering if, instead, i use static information from the pointcut to get the Exception raised by
the intercepted method.. 
i saw something named  CatchClauseSignature... i was wondering if it could be useful.....

here's sample of intercepted methods

EJBX {

  public void setData(XData data) throws XException {
          ....
   }
}

EJBY {

  public void setData(YData data) throws YException {
          ....
   }
}


i was wondering, thus, if i use the CatchClauseSignature, i could
then put following code

 Exception raisedExc = thisJoinPoint.getSignature().getCatchClauseSignature().getParameterType();

throw new ConcernRuntimeException(raisedExc)

so i can raise a ConcernRuntimeException that could wrap XExceptiopn and YException...

wil this work?

thanx in advance and regards for you comments
