RE: [aspectj-users] Scoping or Weaving problem (???)withLTWin anEARon a WAR

Hi Matthew,

I had the same exact problem as Macon. I had an
abstract aspect and then defined a concrete-aspect in
the aop.xml, which resulted in IllegalAccessError and
NoAspectBoundException at runtime on WebLogic. I tried
putting the aop.xml at the CLASSPATH level, but that
didn't solve it either. 

Is defining a concrete aspect in code the only work
around right now? 

Thanks,
Jennie
