java.net.SocketException: Connection reset

【新手求助】《Head First Java》简单Socket通信示例程序运行报错
《Head First Java》第15章介绍Socket通信时的一个示例程序DailyAdvice，包括客户端DailyAdviceClient，服务器DailyAdviceServer。编译通过，开两个命令行窗口，先运行DailyAdviceServer等待客户端的Socket请求，然后在另一个命令行窗口运行客户端DailyAdviceClient，报错:

D:\Code\Head First Java\chap15\DailyAdvice>java DailyAdviceClient
java.net.SocketException: Connection reset

  at DailyAdviceClient.go(DailyAdviceClient.java:15)
  at DailyAdviceClient.main(DailyAdviceClient.java:7)

同时，服务器端报错：
D:\Code\Head First Java\chap15\DailyAdvice>java DailyAdviceServer
java.net.SocketException: select failed
  at java.net.PlainSocketImpl.socketAccept(Native Method)
  at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390)

  at DailyAdviceServer.go(DailyAdviceServer.java:11)
  at DailyAdviceServer.main(DailyAdviceServer.java:30)

奇怪的是，程序不做任何修改，在别人的机子上编译运行均正常。本机环境：Win7 64位，java version 1.6.0_21，防火墙已关闭

程序源码如下：

Server: DailyAdviceServer.java

Java code

import java.io.*;import java.net.*;public class DailyAdviceServer {    String[] adviceList = {"Take smaller bites", "Go for the tight jeans. No they do NOT make you look fat.", "One word: inappropriate", "Just for today, be honest. Tell your boss what you *really* think", "you might want to rethink that haircut."};        public void go() {        try {            ServerSocket serverSock = new ServerSocket(4242);            while (true) {                Socket sock = serverSock.accept();                PrintWriter writer = new PrintWriter(sock.getOutputStream());                String advice = getAdvice();                writer.println(advice);                writer.close();                System.out.println(advice);            }        } catch (IOException ex) {            ex.printStackTrace();        }    }        private String getAdvice() {        int random = (int) (Math.random() * adviceList.length);        return adviceList[random];    }        public static void main(String[] args) {        DailyAdviceServer server = new DailyAdviceServer();        server.go();    }}

Java code

import java.io.*;import java.net.*;public class DailyAdviceClient {    public static void main(String[] args) {        DailyAdviceClient client = new DailyAdviceClient();        client.go();    }        public void go() {        try {            Socket s = new Socket("127.0.0.1", 4242);            InputStreamReader streamReader = new InputStreamReader(s.getInputStream());            BufferedReader reader = new BufferedReader(streamReader);            String advice = reader.readLine();            System.out.println("Today you should: " + advice);            reader.close();        } catch (IOException ex) {            ex.printStackTrace();        }    }}

[解决办法]
个人认为：你的 win7使用的是ip6。
两种方法解决：
1.将你的机器上ip6改成ip4。
2.连接时使用ip6的地址的表现方式：例如：127.0.0.1在ip6应该表示为0

[解决办法]
是不是你“4242”端口被占用了？

[解决办法]
-Djava.net.preferIPv4Stack=true
启动的时候加个参数试试。
