Jakarta ee 如何在JavaEE7中运行WebSocket服务器

我是JavaEE新手，正在尝试构建WebSocket服务器。到目前为止，我有以下课程：

import java.io.IOException;


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

/** 
 * @ServerEndpoint gives the relative name for the end point
 * This will be accessed via ws://localhost:8080/EchoChamber/echo
 * Where "localhost" is the address of the host,
 * "EchoChamber" is the name of the package
 * and "echo" is the address to access this class from the server
 */
@ServerEndpoint("/echo") 
public class EchoServer {
    /**
     * @OnOpen allows us to intercept the creation of a new session.
     * The session class allows us to send data to the user.
     * In the method onOpen, we'll let the user know that the handshake was 
     * successful.
     */
    @OnOpen
    public void onOpen(Session session){
        System.out.println(session.getId() + " has opened a connection"); 
        try {
            session.getBasicRemote().sendText("Connection Established");
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

    /**
     * When a user sends a message to the server, this method will intercept the message
     * and allow us to react to it. For now the message is read as a String.
     */
    @OnMessage
    public void onMessage(String message, Session session){
        System.out.println("Message from " + session.getId() + ": " + message);
        try {
            session.getBasicRemote().sendText(message);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }

    /**
     * The user closes the connection.
     * 
     * Note: you can't send messages to the client from this method
     */
    @OnClose
    public void onClose(Session session){
        System.out.println("Session " +session.getId()+" has ended");
    }

    public static void main(String[] args) throws Exception {

    }
}

我不知道也找不到任何示例来演示如何运行此服务器。任何帮助都将不胜感激。谢谢。

你需要一个容器，比如野蝇或玻璃鱼。@CássioMazzochiMolin你有没有关于如何使用这些容器的例子？@kg这是整本书的主题，不是一个简单的例子。JavaEE开发并不是一件简单的事情。从阅读官方资料（google:JavaEE7WebSockets）开始，你会发现你需要从那里进一步研究什么
