Not able to configure Stomp and SockJS endpoint in Spring MVC.Connection issue !!!

I am implementing Notification System. And want to initialize Socket connection when user Logged In, and show him his notifications, and also if some event happens.

My Code snippet as follows.

websocket.js :

var stompClient = null;
function connect( temp ) {
    alert(temp);
    //var socket = new SockJS("/websock");
    //var socket = new SockJS("/websock"+temp);
    var socket = new SockJS(context_path+"/websock"+temp);
    //context_path == "/SupportCenter"
    stompClient = Stomp.over(socket);
    stompClient.connect({}, function( frame ){
        console.log( "Connected :- "+frame );
        stompClient.subscribe("/topic/notifications", function( notifications ) {
            alert( notifications );
        });
    }, function( error ) {
        alert( error );
    });
    alert();
    getNotifications();
}

function getNotifications() {
    stompClient.send("/app/hello", {}, "Hiiiiii");
}

WebSocketConfig.java :

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) {
        stompEndpointRegistry.addEndpoint("/websock").withSockJS();
    }
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        // TODO Auto-generated method stub
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }
}

WebSocketController.java :

@Controller
public class WebSocketController {

    @MessageMapping(value="/hello")
    @SendTo("/topic/notifications")
    public Notify hello() {
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        Notify notify = new Notify();
        notify.setMessage("Hello World !!!");
        return notify;
    }
}

Some code Hom.jsp :

<script type="text/javascript" src="<c:url value="/resources/js/sockjs.min.js"/>"></script>
<script type="text/javascript" src="<c:url value="/resources/js/stomp.min.js"/>"></script>
<script type="text/javascript" src="<c:url value="/resources/js/websocket.js"/>"></script>


<script type="text/javascript">
$(document).ready(function() {
    //...

    connect( '${nsec}');
});

Why Firefox Console giving XML Parsing Error: no root element found Location: while in Network tab status code is 200 OK. ? What is the cause for this, any suggestions?

Versions I’m using Spring-MVC - 4.1.6 STOMP - 1.7.1 SockJS-client - 1.1.4

Console TAB

Network TAB

solved this by

function connect( temp ) {
    alert(temp);
    //var socket = new SockJS("/websock");
    //var socket = new SockJS("/websock"+temp);
    var socket = new SockJS(context_path+"/websock"+temp);
    //context_path == "/SupportCenter"
    stompClient = Stomp.over(socket);
    stompClient.connect({}, function( frame ){
        console.log( "Connected :- "+frame );
        stompClient.subscribe("/topic/notifications", function( notifications ) {
            alert( notifications );
        });
    getNotifications();//************Changed Here
    }, function( error ) {
        alert( error );
    });
}
