Have you tried running the ant script contained in the jboss-40-install/jboss-aop-jdk50.deployer directory of the jboss-aop-2.0.0.CR4 dist file? The instructions that Kabir talked about are in the ReadMe-AS4.txt file at the same path. One more thing: anonymous wrote : set AVA_OPTS=%JAVA_OPTS%-javaagent:pluggable-instrumentor.jar -Dprogram.name=%PROGNAME% Is AVA_OPTS a typo you did when copying the line to the forum post, or is there a typo in your local run.bat file?
