Jetty websocket client connect to Stomp.js topic channel

Question

I have written a Spring Websocket server which is assessible from a browser via Stomp.js. I am now attempting to implement a Java client in order to connect my server to a secondary system. I am able to connect to the server using the following code

String destUri = "ws://localhost:8080/sample";
    WebSocketClient client = new WebSocketClient();
    SimpleEchoSocket socket = new SimpleEchoSocket();
    try {
        client.start();
        URI echoUri = new URI(destUri);
        ClientUpgradeRequest request = new ClientUpgradeRequest();
        client.connect(socket, echoUri, request);
        System.out.printf("Connecting to : %s%n", echoUri);
        socket.awaitClose(5, TimeUnit.SECONDS);
    } catch (Throwable t) {
        t.printStackTrace();
}

The connection is opened, and now I would like to connect to my topic /price-stream. This is achieved by stomp.js :

stompClient.subscribe('/topic/pricechannel1', renderPrice);

what is the equivalent subscribe method for my Jetty websocket client? I cant find anything in the documentation I have found on the net.

Additional info:

I am trying to implement the stockticker example found here into another project. I can connect to the server through the provided Stomp.js interface in a web browser. Now I am attempting to create a Java client for use within a Swing GUI using Jetty websocket-client to connect.

I need to connect to the price stream, but it seems I am missing some kind of configuration request to latch on as a destination for the topic

In general, plain websocket clients (as the one provided by Jetty) support the websocket standard. STOMP is a protocol that sits on top of that transport.

Here, you'd need to implement your own STOMP client or interface an existing one with the websocket client you're using.

Spring 4.2 (to be published soon) includes a new STOMP client for this particular use case. See the reference documentation of 4.2.RC2.
