I'm not 100% sure how it plays with other bytecode-manipulation products, but most of the time there is no problem. A few suggestions: *Use cavaj or another decompiler to make sure that the classes on your classpath have been aopc'ed. * Pass the -verbose flag in to ant to make sure that you don't have both aopc'ed and non aopc'ed classes on your classpath * Try creating a jboss-aop.xml file and pass in -Djboss.aop.path=PATH_TO_XML and see if that makes any difference Are you saying that without the other frameworks involved it works as expected?
