You need to use [ code ] [ /code ] tags (no spaces inside the "[" and "]" to post xml. Apart from that I am confused :-) ejb-jar.xml: | <interceptor-binding> | Does not exist in EJB 2.1, it was introduced in EJB 3. Also, in EJB 3 the spec-defined interceptors fo not implement org.jboss.aop.advice.Interceptor. jboss.xml: | <interceptor-class>com.presentation.interfaces.TracingInterceptor.java</interceptor-class> | Again this does not exist in jboss.xml. With EJB 2.1 you have the choice between creating a new container configuration with some extra interceptors in jboss.xml or using AOP.
