Topic: TCP/IP Message gets Appended with two dots...(Urgent)

Question

Dear All,
I am working on a requirement where I am sendind a message
(underlying protocol used TCP/IP) using a program
developed using Java Sockets.
It sends the messgage on desired mechine and port but two dots(..)
gets appended with this message .
I am really not able to figure out from where these dots are coming ,
is it the network that appends these dots.
Any clue will be helpful.
An early response is highly appriciable.
Thanks and Regards

You should use a BufferedWriter instead of a PrintWriter, since you're using a BufferedReader. these streams tend to work best in pairs. The readLine requires a newline, so
import java.io.*;
import java.net.*;
public class TestSW
        public static void main(String[]args)
                BufferedWriter output;
                BufferedReader networkBin;
                Socket socket=null;
                try{
                        socket = new Socket("127.0.0.1",5050); // connect to echo server
                        output = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
                        networkBin = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                        output.write("testing");
                        output.newLine();
                        output.flush();
                        System.out.println(networkBin.readLine());
                }catch(IOException e){
                        e.printStackTrace();
                }finally{
                        if(socket != null){
                                try{socket.close();}catch(IOException ce){}
}
