java Glassfish websocket不工作

Question

我正在尝试使用websocket应用程序。作为我使用的Glassfish服务器，工作正常，但我对websocket有问题

在控制台中使用javascript运行html时出现错误404

网络。xml

在src/main/java/websockets中有一个WebSocketServer。爪哇

package websockets;


import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
import java.io.IOException;

import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.OnOpen;
import javax.websocket.OnError;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint("/websocket")
public class WebSocketServer {

    @OnMessage
    public void onMessage(String message, Session session)
    throws IOException, InterruptedException {

        // Print the client message for testing purposes
        System.out.println("Received: " + message);

        // Send the first message to the client
        session.getBasicRemote().sendText("This is the first server message");

        // Send 3 messages to the client every 5 seconds
        int sentMessages = 0;
        while(sentMessages < 3){
            Thread.sleep(5000);
            session.getBasicRemote().
            sendText("This is an intermediate server message. Count: "
                     + sentMessages);
            sentMessages++;
        }

        // Send a final message to the client
        session.getBasicRemote().sendText("This is the last server message");
    }

    @OnOpen
    public void onOpen () {
        System.out.println("Client connected");
    }

    @OnClose
    public void onClose () {
        System.out.println("Connection closed");
    }

    @OnError
    public void onError(Session aclientSession, Throwable aThrowable) {
        System.out.println("Error : " + aclientSession); System.out.println("Error :" + aThrowable);
    }
}

格拉德尔建房时没有出错。当我在http://192.168.37.10:8080/web/page.html（vagrant virtualmachine）中运行应用程序时

抛出错误：

WebSocket connection to 'ws://localhost:8080/web/websocket' failed: Error during WebSocket handshake: Unexpected response code: 404

在glassfish中，将应用程序添加到上下文根：web

怎么了？你能帮助我吗？请谢谢：）
