Although I used jboss as 4.0.5 in the previous post, you should still use 4.2.2. If you are still having problems, paste in your jboss-aop-jdk50.deployer/META-INF/jboss-service.xml. Also, you should be using the pluggable-instrumentor.jar that comes with jboss aop 1.5.6.GA, which is the version that shipped with as 4.2.2. Sometimes you can get problems if the pluggable-instrumentor.jar and jboss-aop-jdk50.deployer have different versions View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123128#...
