 /**

 */


@OnOpen
public void onOpen(Session session){
    System.out.println(session.getId() + " has opened a connection"); 
    try {
        session.getBasicRemote().sendText("Connection Established");
    } catch (IOException ex) {
    }
}

/**

 */
@OnMessage
public void onMessage12(String message, Session session){
    System.out.println("Message from " + session.getId() + ": " + message);
    try {
        session.getBasicRemote().sendText(message);
    } catch (IOException ex) {
    }
}

/**

 * @param session

    System.out.println("Session " +session.getId()+" has ended");
}}

Client code

private void connectWebSocket() {
    URI uri;
    try {
        uri = new URI("ws://localhost:8080/WebApplication1/echo");
    } catch (URISyntaxException e) {
        e.printStackTrace();
        return;
    }

    mWebSocketClient = new WebSocketClient(uri) {
        @Override
        public void onOpen(ServerHandshake serverHandshake) {
            Log.i("Websocket", "Opened");
            mWebSocketClient.send("Hello from " + Build.MANUFACTURER + " " + Build.MODEL);
        }

        @Override
        public void onMessage(String s) {
            final String message = s;
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    TextView textView = (TextView)findViewById(R.id.messages);
                    textView.setText(textView.getText() + "\n" + message);
                }
            });
        }

        @Override
        public void onClose(int i, String s, boolean b) {
            Log.i("Websocket", "Closed " + s);
        }

        @Override
        public void onError(Exception e) {
            Log.i("Websocket", "Error " + e.getMessage());
        }
    };
    mWebSocketClient.connect();
}

I do not know why this error? can someone help me ...

Perhaps you should change the IP address to reflect the IP address on which the Glassfish server is installed on the client.
