hi, first ...thanks for replying... additionally i've put the -javaagent option to JAVA_OPTS, i renamed jboss-aop.deployer to jboss-aop-jdk50.deployer and i modified mbean code="org.jboss.aop.deployment.AspectManagerService" to mbean code="org.jboss.aop.deployment.AspectManagerServiceJDK5" and gave a ClassNotFoundException org.jboss.aop.deployment.AspectManagerServiceJDK5 ....i looked in the jar where the org.jboss.aop.deployment.AspectManagerService is...and indeed i didn't found the class....the class was removed when the jboss4.0.4.GA dist was released ? thanks Viorel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962399#...
