How to send and receive WebSocket messages with Play Framework?

[Jonas]

I implemented an WebSocketController
http://www.playframework.org/documentation/1.2.3/asynchronous#UsingWebSockets
, similar to the one in the Play Framework tutorial, but it doesn't
receive any messages from the client. Have I done anything wrong?

Here is my WebSocketController:

public class TestSocket extends WebSocketController {

public static void hello(String name) {
while(inbound.isOpen()) {
WebSocketEvent evt = await(inbound.nextEvent());
if(evt instanceof WebSocketFrame) {
WebSocketFrame frame = (WebSocketFrame)evt;
System.out.println("received: " + frame.getTextData());
if(!frame.isBinary()) {
if(frame.getTextData().equals("quit")) {
outbound.send("Bye!");
disconnect();
} else {
outbound.send("Echo: %s", frame.getTextData());
}
}
} else if(evt instanceof WebSocketClose) {
System.out.println("socket closed");
}
}
}
}

I have also posted this question on StackOverflow, including a client:

The problem was that I imported
org.jboss.netty.handler.codec.http.websocket.WebSocketFrame instead of
play.mvc.Http.WebSocketFrame

If you want to see another example, have a look at the progress bar demo in the jQuery UI module:

Tried to clone the jqueryui module: 

Cloning into jqueryui-module...

Permission denied (publickey).

fatal: The remote end hung up unexpectedly

What am I doing wrong?

I’m not sure, did you do the following command?

git clone https://github.com/hilton/jqueryui-module.git

Also, I should have mentioned that the web socket controller is:

https://github.com/hilton/jqueryui-module/blob/master/app/controllers/jqueryui/ProgressSocket.java

I followed your instructions in the README:

git clone g...@github.com:hilton/jqueryui-module.git

BUT, I tried using the https link as below, and then in worked fine...

Thanks,
