Hi Kabir, I've created ServiceAOP.zip file and reanmed it to ServiceAOP.aop. The aop file contains 2 directory: META-INF that contains the file: jboss-aop.xml: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> | <aop> | <aspect class="service.ServiceAOPAspect" scope="PER_VM"/> | <bind pointcut="execution(public double service.ServiceAOP-&gt;fattoriale(int))"> | <advice aspect="service.ServiceAOPAspect" name="statistics"/> | </bind> | </aop> The directory service with the class ServiceAOPAspect.class (service is the package of this class). After that I've put the file in jboss-4.2.1.GA/server/default/deploy How can I see if the aop file is deployed correctly? Is the aop file I've created correct? Thanks, bye bye.
