How can i achieve asynchronous callbacks in a stateless/statefull bean? Scenario: A client send a request to a bean (ie do some processing of some large data). The bean returns a answer immidiately to the client, but wants to be able to tell the client on the progress and the final results. The client has a method which is dedicated to handle these callbacks. How can the bean send asynchronous callbacks to the client? I've tried by sending the Method as a argument to the bean: public String getAsynhcString(Method client, String test) and the client invoke this by: test.getAsynhcString(this.getClass().getMethod("callmeback", String.class), "hello"); The callmeback method of the client is on this form: public void callmeback(String res) However, when trying this, I get a marshalling exception: java.io.NotSerializableException: java.lang.reflect.Method which is very unfortunately. wondering if there are any suggestions on how i should accomplish my goal?
