一个简单的网络通信程序，在98下可以通信，在xp下不行，请大虾看看为什么？附程序，很简单！

Socket端的程序：
import java.io.*;
import java.net.*;

public class Server
{
public static final int PORT = 8080;
public static void main(String[] args) throws IOException
{
ServerSocket s = new ServerSocket(PORT);
System.out.println("ServerSocket:" + s);
try
{
Socket socket1 = s.accept();
try
{
System.out.println("Connection to client accepted:" + socket1);
System.out.println("remote getInetAddress()="+ socket1.getInetAddress());
System.out.println("local getLocalAddress()=" + socket1.getLocalAddress());
System.out.println("local getLocalPport()=" + socket1.getLocalPort());
System.out.println("remote getPort()=" + socket1.getPort());
}
finally
{
System.out.println("closing socket");
socket1.close();
}
}
finally
{
s.close();
}
}
}



Client端的程序
import java.io.*;
import java.net.*;

public class Client
{

public static void main(String[] args) throws IOException
{
Socket socket1 = new Socket(args[0],Integer.parseInt(args[1]));
try
{

System.out.println("Connection to server accepted:" + socket1);
System.out.println("remote getInetAddress()="+ socket1.getInetAddress());
System.out.println("local getLocalAddress()=" + socket1.getLocalAddress());
System.out.println("local getLocalPport()=" + socket1.getLocalPort());
System.out.println("remote getPort()=" + socket1.getPort());
}
finally
{
System.out.println("closing socket");
socket1.close();
}

}
}

只是建立一个简单的连接，两个程序在同一台计算机运行，但是98下运行正常，即建立连接，屏幕输出，但是在winxp下不行？为什么？请指点！

先运行java Server以后，屏幕出现
ServerSocket:ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8080]


在运行java Client djd 8080
出现以下错误：
Exception in thread "main" java.net.UnknownHostException: djd
at java.net.PlainSocketImpl.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)
at java.net.Socket.<init>(Unknown Source)
at java.net.Socket.<init>(Unknown Source)
at Client.main(Client.java:9)

在xp下已关闭防火墙

在98下两者就可以成功连接，并按程序输出相应结果！
请各位指教！

现在已经搞清楚了，多谢！
原因是98和xp装的时候用户名（ID）不一样，跟防火墙也有关系！

把错误信息贴出来吧

可能是因为XP的防火墙在捣鬼。关掉它。
