hi, i looks like you've done everything right regarding setting up loadtime weaving (its not advisable to use another version of the instrumentor, but between these releases i dont think thats causing your problem). the problem from your errormsg indicate that aop cant find the class it needs to transform it. could you include your jboss-aop.xml file? it looks like you're trying to transform "thirdparty" class files, this might be the cause of the problem.
