socket 问题

程序如下：
import java.net.*;
//import java.util.*;
import java.io.*;public class Server
{
    public Server()
    {

    }

    public static void main(String[] args) throws IOException
    {
        System.out.println("------365Maga services --------\n");
        System.out.println("Server Starting........");
        ServerSocket server = new ServerSocket(10000);
        while (true)
        {
            Socket s = server.accept();
            System.out.println("Accepting Connection.......");
            System.out.println("A new Thread opened.");
            PrintWriter pw = null;
            pw = new PrintWriter(s.getOutputStream(),true);
            pw.println("sssssssssssssssssfffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff");
            new ServerThread(s).start();
        }
    }
}class ServerThread extends Thread
{
    private Socket s;
    public ServerThread(Socket server)
    {
        this.s = server;
    }
    public void run()
    {
        BufferedReader br = null;
        PrintWriter pw = null;
        try
        {
            InputStreamReader isr;
            isr  = new InputStreamReader(s.getInputStream());
            br = new BufferedReader(isr);
            String m = br.readLine();
            System.out.println("Receive message:  "+m);
            //String subM = m.substring(0,5);
            //if ("Login".equals(subM))
            pw = new PrintWriter(s.getOutputStream(),true);
            pw.println("Your message is:"+ m);
            //System.out.println(m.split(":"));
            System.out.println(m.length());

            if(m.startsWith("Login"))
            {
                System.out.println("one member login.");
            }

        }
        catch(IOException e)
        {
            System.out.println("Server error:"+ e.toString());
        }
        finally
        {
            System.out.println("Connection shuting .......");
            try
            {
                if(br!=null)
                {
                    br.close();
                }
                if(pw!=null)
                {
                    pw.close();
                }
                if(s!=null)
                {
                    s.close();
                }
            }
            catch(IOException e)
            {
                System.out.println("Shuting error:"+e.getMessage());
            }
            //System.out.println("Services Shuted...\n");
            System.out.println("The Thread closed.");
        }
    }

}我以前写的和C++通讯的socket，你参考一下！

我晕，贴错代码了，从来
 public void sendMessage()
 {
 try
 {
 out = new PrintWriter(socketClient.getOutputStream(), true);
 message = "";
 message = message + con_sendMessageTitle1 + sendMessageTitle2;
 message = message + comboBox.getSelectedItem().toString();
 message = message + con_resultTitle1 + textField1.getText() + con_resultTail1;
 message = message + con_resultTitle2 + textField2.getText() + con_resultTail2;
 message = message + "</" + comboBox.getSelectedItem().toString();
 message = message + ">\n" + con_sendMessageTail1 + con_sendMessageTail2;
 out.print(message);
 out.flush();
 log("Sent message is : " + message , 3);
 }
 catch (IOException e)
 {
 log(con_sentMessageError , 2);
 JOptionPane.showMessageDialog(this , con_sentMessageError ,
 con_errorDialogTitle , JOptionPane.ERROR_MESSAGE);
 socketClose();
 }
 } /**
 * This method's function is that accept the stream from server and
 * transfer inFile() to analyse this stream. 
 * Return null if system could not accept the message at definite time.
 */
 public void socketIncept()
 {
 try
 {
 String str = new String();
 message = "";
 in = new BufferedReader(
 new InputStreamReader(socketClient.getInputStream()));
 while ((str = in.readLine()) != null)
 {
 message = message + str + "\n";
 str = str.trim();
 if (str.endsWith(con_sendMessageTail2))
 {
 break;
 }
 }
 log("Accept message is : " + message , 3);
 }
 catch (IOException e)
 {
 log(con_timeOutError , 1);
 JOptionPane.showMessageDialog(this , con_timeOutError ,
 con_errorDialogTitle , JOptionPane.ERROR_MESSAGE);
 socketClose();
 return;
 }
 inFile();
 }

socket.getOutputStream 或者 socket.getInputStream 之后，不要简单地构造成 PrintWriter 和 Reader，应该与 C++ 约定好编码后，使用 InputStreamReader 和 OutputStreamWriter 指定相应的编码。详情请参考文章：
