Hi Matteo,
does your sample-code work? Is everything okay with your WebSocket-server? What
kind of server with which WebSocket-Implementation are you using?
To make sure that we are talking about the same thing, I changed my code so
test the WebSocket against a publicly WebSocket test-server
("http://www.websocket.org/echo.html";).
Here is the code:
> /**
> * @ignore(WebSocket)
> */
> qx.Class.define("testwebsocket.WebSocket",
> {
> extend : qx.core.Object,
>
> construct : function()
> {
> this.base(arguments);
>
> this.socket = new WebSocket('ws://echo.websocket.org/');
>
> // register native event-listeners
> this.socket.addEventListener("open", this.onSocketOpen , false);
> this.socket.addEventListener("message", this.onSocketMessage , false);
> this.socket.addEventListener("close", this.onSocketClose , false);
> this.socket.addEventListener("error", this.onSocketError , false);
> },
>
> members :

> // event-handlers
> onSocketOpen : function(e) {
> console.log("Connection opened");
> },
>
> onSocketMessage : function(e) {
> console.log("Message received: " + e.data);
> },
>
> onSocketClose : function(e) {
> console.log("Connection closed");
> },
>
> onSocketError : function(e) {

> }
> }
> });
To test it, create an instance of this class and assign it to a global variable:
> ws = new testwebsocket.WebSocket();
Now start you application and open the developer-console of your browser. You
should already see the log "Connection opened"). Then send a message to the
server, just type ws.send("You message text") into the browser-console and the
server will immediately echo it.
Best,
Andreas
