Re:Help with code for server client

Question

Hi i am struggling to adapt code for UDPServer and client programs.
how can i adapt the following server code to add a message before replying to the client?
import java.net.*;
import java.io.*;
public class UDPServer2{
public static void main(String args[]){
     DatagramSocket aSocket = null;
          try{
          aSocket = new DatagramSocket(9000);
                         // create socket at agreed port
               byte[] buffer = new byte[1000];
               while(true){
                    DatagramPacket request = new DatagramPacket(buffer, buffer.length);
                    aSocket.receive(request);
               DatagramPacket reply = new DatagramPacket(request.getData(), request.getLength(),
                    request.getAddress(), request.getPort());
                         aSocket.send(reply);
          }catch (SocketException e){System.out.println("Socket: " + e.getMessage());
          }catch (IOException e) {System.out.println("IO: " + e.getMessage());
          }finally {if(aSocket != null) aSocket.close();}
any help would be much appreciated i have tried altering the aSocket.send(reply) line but to no avail.
thank you in advance
