Thanks for the explanation...
This is what i do but when i tried to establish the connection with the server... it refused it.... where i did wrong?
PrintWriter out = null;
          BufferedReader in = null;
          Socket mySocket1=null;
          Socket mySocket2 = null;
          try
               String host;
               if (args.length > 0)
               host = args[0];
               } else
               host = "localhost";
                    try
                    mySocket1 = new Socket(host, 8997);
                    mySocket1.setSoTimeout(1000);
                    }catch(SocketException se)
                         System.err.println("Error Connecting to socket :" +se);
                    mySocket1.close();
                    try
                         mySocket2 = new Socket("localhost", 8998);
                    }catch(SocketException se)
                         System.err.println(" Unable to connect to socket:" + 8998);
                    while(true)
                         //mySocket2 = new Socket("localhost", 8997);
                         out     = new PrintWriter(new OutputStreamWriter(mySocket2.getOutputStream()));
                         in = new BufferedReader(new InputStreamReader(mySocket2.getInputStream()));
                         Thanks for your help...
