Connection reset 错误，我的网络编程~~

[wp7615590]

先看下原代码：
客户端:
public class Client
{
public static void main(String[] args)
{
Socket so=null;
BufferedReader in=null;
PrintWriter out=null;
try{

so=new Socket(InetAddress.getLocalHost().getHostAddress(),8811);
in=new BufferedReader(new InputStreamReader(so.getInputStream()));
out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(so.getOutputStream())));

System.out.println (in.readLine());
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
服务器端:
public class Server
{

public static void main(String[] args)
{
ServerSocket ss=null;
Socket so=null;
BufferedReader in=null;
PrintWriter out=null;
try{
ss=new ServerSocket(8811);
so=ss.accept();
in=new BufferedReader(new InputStreamReader(so.getInputStream()));
out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(so.getOutputStream())));
out.println("连接成功");
System.out.println ("bb");

}
catch(Exception e1)
{
System.out.println ("Server"+e1.toString());
}

}
}

正确的是客户端打印"连接成功"
可是却抛异常了
请问什么地方不对

用Socket时，Server和Client有任意一方关闭连接(退出也算)另一方都会有异常抛出

... ...
out=new PrintWriter(new BufferedWriter(new OutputStreamWriter(so.getOutputStream())));
out.println("连接成功");
out.flush(); // 添加
