How to Define cliend as a java class not as a browser for Spring WebSocket?

I want to transffer high frequency realtime data from one location to othere using WebSocket in Spring. I have done this task, If I transfer data from server to browser.But My need is different, I have to send data from server to client(but client will be java class rather than browser).I have done code Server side as bellow:-

 String dcEndPoint =       DiUtils.getPropertyValue(LGRConstants.DATACENTER_WEBSOCKET_ENDPOINT);
    List<Transport> transports = new ArrayList<Transport>(2);
    transports.add(new WebSocketTransport(new StandardWebSocketClient()));
    transports.add(new RestTemplateXhrTransport());

    SockJsClient sockJsClient = new SockJsClient(transports);
    //sockJsClient.doHandshake(new DCWebSocketHandler(), dcEndPoint);
    //sockJsClient.start();
    AbstractWebSocketHandler webSocketHandler = new TextWebSocketHandler() {
        @Override
        public void afterConnectionEstablished(WebSocketSession session) throws Exception {
            loggingServiceInterface.logInfo("connected");

        }

        @Override
        public void handleMessage(WebSocketSession session,
                WebSocketMessage<?> message) throws Exception {
            super.handleMessage(session, message);

            session.sendMessage(null);
        }
    };

        sockJsClient.doHandshake(webSocketHandler, new WebSocketHttpHeaders(), 
                new URI(dcEndPoint)).get(3000, TimeUnit.SECONDS);

But problem is how to define java client for recieving data.Please anyone guide me.Is any other option there for doing same thing.Am I going wrong please guide me.
