I read through some of those.
I have my server code here:

Code:

import java.io.*;
import java.net.*;
class login {
   private static BufferedReader stdin = 
      new BufferedReader( new InputStreamReader( System.in ) );



   public static void main(String[] args) throws IOException, ServerSocketException, SocketException  {
      ServerSocket server = new ServerSocket(2011, 3);
      Socket incoming = server.accept();
      System.out.println("Socket Opened");
      BufferedReader in = new BufferedReader
         (new InputStreamReader(incoming.getInputStream()));
      PrintWriter out = new PrintWriter
         (incoming.getOutputStream(), true /* autoFlush */);

      boolean done = false;
      while (!done) {
         String line = in.readLine();
         String next = null;
         String[] temp;
         System.out.println(line);
         if (line.trim().equals("login")) {
            next = "login";
            out.println("login");
         } 
         if (line.trim().equals("BYE")) done = true;
         if (next == "login") {
            temp = line.trim().split(":");
            out.println("Welcome " + temp[0]);
         }
      incoming.close();
      }
   }
}

I don't know what I am doing wrong, but it seems to crash right after it prints their message on screen.

I think this is because it is unable to write back to the socket.

Is there a function I should be using other than out.println?

Here is the output from my this script.
Notice I messaged the script a. It also gives the same problem when I message real commands such as login and BYE.

Code:

C:\Program Files\Java\jdk1.6.0_01\bin>java login
Socket Opened
a
