两个java类一个jsp:

ServerAccept负责监听接口8091,当客户端与端口建立连接时,该类通过一个新线程启动ServerEchoRequest类处理请求内容,并保存在目录下的request.text中。

1.ServerAccept:

/**

 * @author lucifer
 */
import java.net.*;
import java.io.*;


public class ServerAccept implements Runnable{
   final static int LISTEN_PORT = 8091;
   public void run(){
      ServerSocket server = null;
      try{
        server = new ServerSocket(LISTEN_PORT);
        System.out.PRintln("正在等待连接");
      }
      catch(IOException e){
        System.out.println("不能连接到端口:" +
            LISTEN_PORT + ":" +
            e.getMessage());
        System.exit(0);
      }
      while(true){
        try{
           new Thread(new ServerEchoRequest(server.accept())).start();
           System.out.println("启用一个连接");
        }
        catch(IOException e){
           System.out.println("不能接受数据:" + e.getMessage());
        }
      }
   }

public static void main(String[] args){
      new Thread(new ServerAccept()).start();
   }
}

2.ServerEchoRequest:


/**
 *
 * @author lucifer
 */
import java.io.*;
import java.net.*;

public class ServerEchoRequest implements Runnable{
   Socket m_socket = null;
   final static int MAX_BUFF = 4000;
   private final static int TIMEOUT = 3000;

public ServerEchoRequest(Socket socket)throws SocketException{
      m_socket = socket;
   }

public void run(){
      try{
        getClient(m_socket);
      }
      catch(IOException e){
        System.out.println(e);
        System.exit(0);
      }
      catch(ClassNotFoundException ex){
        System.out.println(ex);
        System.exit(0);
      }
   }

protected void getClient(Socket socket)throws IOException,ClassNotFoundException{
      DataInputStream in = new DataInputStream(m_socket.getInputStream());
      String s;
      File f =new File("request.text");
      PrintWriter fileout = new PrintWriter(new FileWriter(f));
      while((s = in.readLine())!=null){
        System.out.println(s);
        fileout.println(s);
        fileout.flush();
      }
   }
}


3.JSP页:
