Has socket io server java implementation stopped working along with Jetty 11?

[yashsharm]

Based on socket io server Java documentation (https://socketio.github.io/engine.io-server-java/using.html#jetty-server) and Jetty 11 APIs, it appears there is lot of change in the Jetty APIs for websocket. Jetty has deprecated WebSocketUpgradeFilter and removed WebSocketServlet and WebSocketServletFactory. With the introduction of JettyWebSocketServlet Jetty has take all implementation in its own hands.
I am trying to use the Jetty websocket adapter provided by engine-io-server-jetty(JettyWebSocketHandler) along with JettyWebSocketServlet and JettyWebSocketCreator. But it is not working. Can someone please help ?

Following is my code.

package com.egain.live.framework.socketIO;

import io.socket.engineio.server.Emitter;
import io.socket.engineio.server.EngineIoServer;
import io.socket.engineio.server.EngineIoServerOptions;
import io.socket.engineio.server.JettyWebSocketHandler;

import org.eclipse.jetty.websocket.server.JettyWebSocketCreator;
import org.eclipse.jetty.websocket.server.JettyWebSocketServlet;
import org.eclipse.jetty.websocket.server.JettyWebSocketServletFactory;

import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;

;

@WebServlet(name = "Socket IO Servlet", urlPatterns = { "/socketiofw/*" })
public class SocketIoServlet extends JettyWebSocketServlet {

private EngineIoServer mEngineIoServer;
private SocketIoServer mSocketIoServer;

@Override
public void configure(JettyWebSocketServletFactory factory) {
    EngineIoServerOptions options = EngineIoServerOptions.newFromDefault();
    options.setAllowSyncPolling(true);
    options.setPingInterval(10000);
    this.mEngineIoServer = new EngineIoServer(options);
    mSocketIoServer = new SocketIoServer(mEngineIoServer);
    factory.setIdleTimeout(Duration.ofSeconds(600L));
    //factory.register(MySocket.class);
    factory.addMapping("/", new MyJettySocketCreator(mEngineIoServer));
}

public SocketIoServlet() {

}

@Override
protected void service(HttpServletRequest request, HttpServletResponse response) throws IOException {
    mEngineIoServer.handleRequest(request, response);
    SocketIoNamespace namespace = mSocketIoServer.namespace("/");
    mEngineIoServer.on("connection", new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            SocketIoSocket socket = (SocketIoSocket) args[0];
            // Do something with socket

            // Attaching to 'foo' event
            socket.on("foo", new Emitter.Listener() {
                @Override
                public void call(Object... args) {
                    System.out.println("Received 'foo' event"+args[0]);
                    socket.send("toClient", args[0]);
                }
            });

            socket.send("toClient", "Hello from socket io server", 1);
        }
    });

    // Broadcasting event 'foo' with args 'bar arg' to room 'room'
    //namespace.broadcast("room", "foo", "bar arg");


}

}

class MyJettySocketCreator implements JettyWebSocketCreator {
EngineIoServer mEngineIoServer;
MyJettySocketCreator(EngineIoServer engineIoServer) {
System.out.println("MyJettySocketCreator constructor");

    mEngineIoServer = engineIoServer;
}

@Override
public Object createWebSocket(JettyServerUpgradeRequest jettyServerUpgradeRequest, JettyServerUpgradeResponse jettyServerUpgradeResponse) {
    return new JettyWebSocketHandler(mEngineIoServer);
}

}
