    EJB3 container configuration and interceptors

      how can i add custom interceptors in ejb3??

      with ejb2 i have been using the standardjboss.xml to insert my own interceptors into the standard container interceptor stack (see ActivityInterceptor below). i also used a client side invocation interceptor to make some client information ride with the invocation payload (further below)

      with my beans no on ejb3 the stadardjboss.xml configuration is just ignored? is there a new container configuration file for ejb3? i'm cluless

      server side interceptor

          You can add your own interceptors in ejb3-interceptors-aop.xml for example. I guess you mean not the interceptors from the spec because those interceptors are jbossAOP interceptors.

          You can create your own interceptor stacks their!

            thanks thomas,

            i tried to insert my interceptor to one of the existing stacks in ejb3-interceptors-aop.xml but that started throwing NullPointer exceptions.

            what i want to do is intercept ALL stateless bean calls on the client and the server. i used the existing stack called StatelessSessionClientInterceptor and Stateless Bean but that as i said ran into exceptions. i'm not sure if the order of interception matters.

            did your work involve intercepting all beans or one particular bean calls.

            thanks
            F

              I did it for all session beans. But you can also have a stack for a specific bean.

              I don't know where your problem comes from because I have not enough information.

              Did you deploy your interceptor classes correctly?

              I have a simple interceptor test on http://www.strace.org/~tterm/jboss-testcase.zip

              You should comment out the metadata stuff their because it will throw an exception but without it should work fine.

              Regards,
              Thomas
