Kabir, To be more specific i am trying to configure logging for EAR file. So, my interceptor should be accessible by both web(.WAR) and ejb(.JAR) files. I created mylogging.aop file with jboss-aop.xml file in meta-inf dir. and copied it to deploy dir of jboss. I still get: java.lang.ClassNotFoundException: log.logging.trace.MyMethodInterceptor do i have to add this .aop file to application.xml and copy the .aop file to root of EAR file? Please suggest me. Thanks, Srikanth. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4193782#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
