How to implement the WebSocket protocol in a GWT project?

Question

Google Web Toolkit

Good day to all. I've been trying for a week now to implement a simple way to exchange messages over the Websocket protocol. Nothing works, I don’t even know how, but the example I found on the net is not working. ( www.youtube.com/watch?v=NN5qmxb15lY)
Has anyone already implemented something like this? Please share your solution.

Answer 1

On the client side, it is implemented in elementary native JS.

I haven't tried it on the server side, but in theory you can implement it on the latest tomcat

Upd. Watched the video. Didn't know about this library. I'll take it on board.
In any case, I advise you not to bother with wrappers for js on the client first, but simply test the connection with a valid websocket with native js.
For example www.websocket.org/echo.html.

bombermine.ru - they definitely have websockets, I read somewhere for a long time that something like GWT

Answer 3

Here is an example of a wrapper in JSNI from a developer from Google https://github.com/realityforge/gwt-websockets
Here you can track the request to add web sockets features to GWT https://code.google.com/p/google-web-toolkit /issue...
