在java中与服务器和客户端WebSocket正确通信

    try {
        serverSocket = new ServerSocket(10007);
    }
    catch (IOException e)
    {
        System.err.println("Could not listen on port: 10007.");
        System.exit(1);
    }

    System.out.println ("Waiting for connection.....");

    try {
        clientSocket = serverSocket.accept();
    }
    catch (IOException e)
    {
        System.err.println("Accept failed.");
        System.exit(1);
    }
    System.out.println ("Connection successful");

当我试图从客户端连接时,似乎整个事情在我收到消息时都不起作用 waiting for connection... . 我连接客户端的代码如下:

 String serverHostname = new String("ip");

    if (args.length > 0)
        serverHostname = args[0];
    System.out.println("Attemping to connect to host " +
            serverHostname + " on port 10007.");

    Socket echoSocket = null;
    PrintWriter out = null;
    BufferedReader in = null;

    try {
        echoSocket = new Socket(serverHostname, 10007);
        out = new PrintWriter(echoSocket.getOutputStream(), true);
        in = new BufferedReader(new InputStreamReader(
                echoSocket.getInputStream()));
    } catch (UnknownHostException e) {
        System.err.println("Don't know about host: " + serverHostname);
        System.exit(1);
    } catch (IOException e) {
        System.err.println("Couldn't get I/O for "
                + "the connection to: " + serverHostname);
        System.exit(1);
    }

这会是什么问题?
