Hello Clebert, so now let's come to the details and sorry for the long response time. I have a lot to do at the moment. The interceptors are requested during an ejb3 method call. The client side interceptor code is the following: | public class ExampleClientInterceptor implements Interceptor, Serializable { | private static Logger logger = Logger.getLogger(ExampleClientInterceptor.class); | | public String getName() { | return "ExampleClientInterceptor"; | } | | public Object invoke(Invocation invocation) throws Throwable { | logger.debug("Client: request"); | SimpleMetaData metaData = invocation.getMetaData(); | metaData.addMetaData("tag", "attr", "Hello JBoss;-)"); | Object obj = invocation.invokeNext(); | logger.debug("Client: response"); | return obj; | } | } You can see I just add a simple string to the metadata which should be read later from the server side interceptor. The server side interceptor has the following code: public class ExampleServerInterceptor implements Interceptor{ | private static Logger logger = Logger.getLogger(ExampleServerInterceptor.class); | | public String getName(){ | return "ExampleServerInterceptor"; | } | | public Object invoke(Invocation invocation) throws Throwable{ | logger.debug("Server: request"); | SimpleMetaData metaData = invocation.getMetaData(); | String str = (String)metaData.getMetaData("tag", "attr"); | logger.debug("Output from metaData: " + str); | Object obj = invocation.invokeNext(); | logger.debug("Server: response"); | return obj; | } | } The interceptors are both registerded in the ejb3-interceptors-aop.xml which looks like the following: | <aop> | <interceptor class="de.example.ExampleClientInterceptor" scope="PER_VM"/> | <interceptor class="de.example.ExampleServerInterceptor" scope="PER_VM"/> | | .... | | <stack name="StatelessSessionClientInterceptors"> | <interceptor-ref name="de.example.ExampleClientInterceptor"/> | ... | </stack> | ... the same for the other client side stacks like stateful and so on | | server side stuff | | <domain name="Stateless Bean"> | <bind pointcut="execution(public * *->*(..))"> | <interceptor-ref name="de.example.ExampleServerInterceptor"/> | ... | </domain> | | ... the same for the other session bean stuff | | </aop> | So if you invoke an ejb3 method then you get allways the exception I described before and you will never come to the server side interceptor. I don't know if I do something wrong here but as I said before it works fine until JBoss4.0.3SP1. It would be very nice if we could sorting out this things because I need it to finish an performance instrumentation project. You can download the test project described before from http://www.strace.org/~tterm/jboss-testcase.zip (You can contact me private if you use this domain and put the username before the @ sign). If you need an ejb project for testing this things I can give you also an test project. Just let me know. Thanks in advance.
