sockjs

I would like to understand how convertAndSendToUser works in Spring SockJS+Websocket framework. In client, we would connect as stompClient.connect(login, password, callback()) which will result in connect request with "Stomp credentials" of login and password, that can be seen e.g. if we handle SessionConnectEvent http://www.sergialmar.com/2014/03/detect-websocket-connects-and-disconnects-in-spring-4/ But it remains unclear to me whether this will be the "user" meant in server-side send operation to a queue: simpMessagingTemplate.convertAndSendToUser(username, "/queue/reply", message); The

In a working Spring MVC 4.0.2 project running under Tomcat 7.0.50, I'm trying to implement Spring Websocket with simple broker and sockjs stomp endpoint, following the official reference . So, in the contextConfigLocation (DistpacherServlet property) I've add a value "websocket-config.xml" which contains: > <websocket:message-broker application-destination-prefix="/app" > > <websocket:stomp-endpoint path="/monitor"> > <websocket:sockjs /> > </websocket:stomp-endpoint> > <websocket:simple-broker prefix="/topic"/> > </websocket:message-broker> In eclipse console (catalina log) when I start

I am trying to streaming time series data using Springframework SimpMessagingTemplate (default Stomp implementation) to broadcast messages to a topic that the SockJS client subscribed to. However, the messages is received out of order. The server is single thread and messages are sent in ascending order by their timestamps. The client somehow received the messages out of the order. I am using the latest release version of both stompjs and springframework (4.1.6 release). Found the root cause of this issue. The messages were sending in "correct" order from the application implementation

I have, what I think to be, a very simple Spring WebSocket application. However, I'm trying to use path variables for the subscription as well as the message mapping. I've posted a paraphrased example below. I would expect the @SendTo annotation to return back to the subscribers based on their fleetId . ie, a POST to /fleet/MyFleet/driver/MyDriver should notify subscribers of /fleet/MyFleet , but I'm not seeing this behavior. It's worth noting that subscribing to literal /fleet/{fleetId} works. Is this intended? Am I missing some piece of configuration? Or is this just not how it works? I'm

Is there a way to use WebSockets with SockJS client and Spring 4 server but not using STOMP? Based on this tutorial from Spring's website, I know how to set up a WebSocket based application using Stomp and Spring 4. On the client side, we have: var socket = new SockJS('/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); }); }); And on the server side, we have the following in the controller:
