Simple client / server not success

[adeeb alexander]

Hi,
I have a echo server and echo client. whenever i send a line to server, it is seen at the server. But i want to send the line through the server and should receive at client. How can i do so. Some body please help. Here's the code.

EchoServer

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

public class EchoServer
{
   public static void main(String args[])
     {
        try
         {
           ServerSocket sskt=new ServerSocket(1001);
           System.out.println("Waiting for the Client.... ");
           Socket cskt=sskt.accept();
           System.out.println("Client found");
           BufferedReader sr=new BufferedReader(new InputStreamReader(cskt.getInputStream()));
           PrintWriter pw=new PrintWriter(cskt.getOutputStream(),true);
           String line;
           while((line=sr.readLine())!=null)
             {
                System.out.println("From Client :"+line);
                pw.println(line);
             }
           sr.close();
           pw.close();
           cskt.close(); 
          }catch(Exception e)
              {
                  System.out.println(e);
               }
        
     }
} 

EchoClient

  
import java.net.*;
import java.io.*;
import java.util.*;
public class EchoClient
{
   public static void main(String args[])
     {
        try
         {
           Socket cskt=new Socket("127.0.0.1",1001);
           BufferedReader sr=new BufferedReader(new InputStreamReader(cskt.getInputStream()));
           PrintWriter pw=new PrintWriter(cskt.getOutputStream(),true);
           Scanner kbr=new Scanner(System.in);
           System.out.println("enter message line by line. enter 'end' to stop");
           String line;

           while(true)
             {
                line=kbr.nextLine();
                if(line.equals("end"))
                    break;
                pw.println(line);
                line=sr.readLine();
                System.out.println("From Server :"+line);
             }
           sr.close();
           pw.close();
           cskt.close(); 
          }catch(Exception e)
              {
                  System.out.println(e);
               }
        
     }
}

Please tell me what are the changes required.
Thanks and Regards

The code as you posted works fine for me:

   
C:\junk>java -version
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)

C:\junk>javac EchoClient.java

C:\junk>javac EchoServer.java

C:\junk>java EchoClient
enter message line by line. enter 'end' to stop
asdf
From Server :asdf
sdf
From Server :sdf
sadf
From Server :sadf
asdf
From Server :asdf
asdf
From Server :asdf
sdf
From Server :sdf
asdf
From Server :asdf
asdf
From Server :asdf

By the way, using code that depends on end-of-line markers (BufferedReader, Scanner) is not recommended when programming sockets as EOL is OS-dependent.
