Examples of org.jboss.remoting.callback.Callback

org.jboss.remoting.callback.Callback
This is the class to use for sending callback payloads from the server handler to the callback listener. @author Tom Elrod

      // We send the message to the client on the current thread. The message is written onto the
      // transport and then the thread returns immediately without waiting for a response.


      ClientDelivery del = new ClientDelivery(ref.getMessage(), consumer.getID(), deliveryID, ref.getDeliveryCount());


      Callback callback = new Callback(del);


      try
      {
         // one way invocation, no acknowledgment sent back by the client
         if (trace) { log.trace(this + " submitting message " + ref.getMessage() + " to the remoting layer to be sent asynchronously"); }
