[jboss-user] [JBoss AOP] - Not quite getting it (aka noclassdeffound)

Sat Mar 3 18:07:16 EST 2007

I am new to AOP and have been attempting to get a basic trace advice running.  I am using jdk 5.0 and annotations, JBossAS 4.0.5.  I created my class and annotated a method but nothing happened.  I suspected that I needed to set 'EnableLoadtimeWeaving' to true because I did not use any aopc.

Is that a correct understanding of how it works?

I set the flag to true and then I got a null pointer exception.  See trace 1.
I then downloaded  1.5.4 SP2  TWICE but it would not unzip, so I downloaded 1.5.4 SP1 and used the jboss-aop-jdk50.deployer from that.  I then got a noclassdeferror for AOPScopedClassLoaderHelper.  See trace 0.

I searched for a jar with that class but could not find one so I am pretty much dead in the water.  Any help would really be appreciated.

Thanks

TRACE 0.
