public class Client{
   public static void main(String[] args){
      try{
   Socket  telnet=new Socket(本地机名,4413);
   telnet.setSoTimeout(20000);
DataOutputStream out=new DataOutputStream(telnet.getOutputStream());
  out.writeChars("BYE");
  out.flush();
  }
catch(IOException e){
    System.out.println("失败   3 "+e);
   }
}
}

先运行server端的TestEcho,
(1)如果使用'telnet localhost 4413'命令,则一切正常,
窗口显示"Hello! Enter BYE to exit." ,输入"BYE"即可退出.
(2)但运行client端的Client则出现
"失败  2 java.net.SocketException: Connection reset by peer: JVM_recv in socket input stream read"


请各位大侠指教!!
分一定会送!!

我在后面加上一点东西后就好啦，我也不知道为什么
DataOutputStream out1=new DataOutputStream(telnet.getOutputStream());
           out1.writeChars("BYEn");
           out1.flush();
 
 BufferedReader in = new BufferedReader(new InputStreamReader(telnet.getInputStream()));
     PrintWriter out =  new PrintWriter(new BufferedWriter(new OutputStreamWriter(telnet.getOutputStream())), true);
           String  str = in.readLine();
           System.out.println(str);
 out.println("sdfewrw");
 str = in.readLine();
           System.out.println(str);
 out.println("BYE");
 
 str = in.readLine();
           System.out.println(str);

在 client端
将这句： DataOutputStream out=new DataOutputStream    (telnet.getOutputStream());
 out.writeChars("BYE");
  
改为：   PrintWriter out = new PrintWriter (telnet.getOutputStream(), true)  ;           
  out.println("BYE");
我以试过的。
