Play Framework WebSocketController

public class WebSocket extends WebSocketController {
public static void test(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());
                    }
                }
            } 
        }
     }
 }

Solution

You have the basic of making work a single socket. However, each socket you are creating uses your socket events. Since each of the sockets would equal a thread, you need to send the event for each socket you can have. This is why when a new socket is open you need to map it in an array of sockets.
