Spring 4 websocket And stomp - controller is not reached

I'm using the official example (Greeting example) of spring located in:

http://spring.io/guides/gs/messaging-stomp-websocket/

everything seems to work just fine, when i press the connect i can see that the connection agaisnt the server is being made.

But, after connection when i submit a "name" to the server i get no error and no request reaches the GreetingController.

I tried to put the log level on trace and i see the following lines when i execute the "send":

22 Ar 2014 17:10:52 DEBUG DispatcherServlet - Successfully completed request
22 Apr 2014 17:10:52 DEBUG ExceptionTranslationFilter - Chain processed normally

22 Apr 2014 17:10:56 DEBUG SimpAnnotationMethodMessageHandler - Handling message, lookupDestination=/hello

any ideas?

P.S , here is the part of the js code i use (identical to the website):

    function connect() {
        var socket = new SockJS('/MyWebApp/hello');
        stompClient = Stomp.over(socket);
        stompClient.connect({}, function(frame) {
            setConnected(true);
            console.log('Connected: ' + frame);
            stompClient.subscribe('/topic/greetings', function(greeting){
                showGreeting(JSON.parse(greeting.body).content);
            });
        });
    }

    function disconnect() {
        stompClient.disconnect();
        setConnected(false);
        console.log("Disconnected");
    }

    function sendName() {
        debugger;
        var name = document.getElementById('name').value;
        stompClient.send("/app/hello", {}, JSON.stringify({ 'name': name }));
    }

Well, the server is catching the message but it is doing nothing with that.So, I think that you should:

  1. Pay attention to this line "config.setApplicationDestinationPrefixes("/app");" on WebSocketConfig class;
  2. Be sure that your Controller is anottated with @Controller and the method with @MessageMapping("/hello");
