Hi
thanx all of you for replying. Have a look on the following code:-
it is a simple UDP Echo client whose function is to echo back thorugh the server whatever typ by the user

import java.io.*;
import java.net.*;
public class UDPEchoClient
{
public static void main (String args[])
{
try
{
InetAddress host =InetAddress.getByName("localhost");
BufferedReader kbd = new BufferedReader(new InputStreamReader(System.in));
byte [] buf =new byte[1024];
DatagramSocket ds = new DatagramSocket();
DatagramPacket dp;
String line;
while((line=kbd.readLine())!=null)
{
dp =new DatagramPacket (line.getBytes(),line.length(), host,7);
ds.send(dp);
ds.receive(dp);
System.out.println(new String(dp.getData()));
}

}
catch(IOException e)
{
System.err.println(e);
}
}
}

My question is how to ammend this program inorder to work this program as a Tftp client to issue a "Read" rqeuest to the server to get the file.
Thanx
