client and server program in JSP. (moved to java)

[rajbala]

Hi all,
I am a newbie to JSP. I had a program in client and server by using java.

But i want the same program in JSP. Please help me.


server:

     // TCP server which waits for messages from a client - non threaded
import java.io.*;
import java.util.*;
import java.net.*;

public class TCPserver1 
{
public static void main(String args[])
{
        int receivePort=9000;             // port to receive TCP connections
         Socket socket=null;
         while(true)                      // when client closed start again
            try
                {
                  System.out.println("TCP server starting: IP address " 
                       + InetAddress.getLocalHost().toString() + " port " + receivePort );
                  ServerSocket serverSocket = new ServerSocket(receivePort);
                  socket = serverSocket.accept();    // Wait for client to connect.
                  System.out.println("Client connect from IP address " + socket.getInetAddress()
                                  + " port " + socket.getPort());
                  ObjectInputStream br  = new ObjectInputStream( ( socket.getInputStream() ) );
                  ObjectOutputStream pw = new ObjectOutputStream( socket.getOutputStream() );
                  while(true)                       // receiving messages from client
                    try
                    {
                      String code = (String) br.readObject();
                      System.out.println( "Server received string: '" + code + "'");
                    }
                    catch (Exception se) {System.err.println("closing connection"); break;}
                  serverSocket.close();
                }
            catch (Exception se) {System.err.println("run() " + se); }
        }
}

client

// TCP client which sends a message to a server 

import java.io.*;
import java.util.*;
import java.net.*;

public class TCPclient
{
private final static BufferedReader in = new BufferedReader(new InputStreamReader(System.in));


public static void main(String args[])
{
   System.out.println("enter message to send to server");
   String remoteIPaddress="127.0.0.1";
   int remotePort=9000;
   try
       {
        Socket socket1 = new Socket( remoteIPaddress, remotePort );   
        ObjectOutputStream objOut = new ObjectOutputStream( socket1.getOutputStream() );
        System.out.println("Server contacted OK , enter text to send " );
        while(true)
            {
             String s = in.readLine();
             objOut.writeObject(s);         // send message
            }  
        }
    catch (IOException e) {System.err.println("TCP client error " +  e); }
 }

Raju, JavaScript and JSP are very different. You'll need to post in another thread if you're looking for good replies. Try reading the JS vs. JSP post at the top of the category. I hope you have better luck in another thread.

[maverick19]

use the page directive to import the java code to your jsp
then you can easily call the method in the jsp its simple java there

<%@ page import="mypackage.*" %> 

and somewhere in the jsp 
<%
Myclass check = new Myclass()
check.mymethod();
%>

You could use a jsp for the client actions and a servlet for the server actions

yes it's working thank you to all for suggestion.
