I'm a real newbie to java, so please excuse me if this is a hopelessly straightforward problem.

I have the following from my java game server:

// Get input from the client
    DataInputStream in = new DataInputStream (server.getInputStream());
    PrintStream out = new PrintStream(server.getOutputStream());
    disconnect=false;

    while((line = in.readLine().trim()) != null && !line.equals(".") && !line.equals("") && !disconnect) {
        System.out.println("Received "+line);

      if(line.equals("h")){
          out.println("h"+EOF); // Client handshake
          System.out.println("Matched 1");

      }else if (line.equals("<policy-file-request/>")) {
          out.println("..."+EOF); // Policy file
          System.out.println(server.getInetAddress()+": Policy Request");
          disconnect=true;
          System.out.println("Matched 2");

      }else if(line.substring(0,3).equals("GET")||line.substring(0,4).equals("POST")){
          out.println("HTTP/1.0 200 OK\nServer: VirtuaRoom v0.9\nContent-Type: text/html\n\n..."); // HTML status page
          disconnect=true;
          System.out.println("Matched 3");


      } else {
          System.out.println(server.getInetAddress()+": Unknown command, client disconnected.");
          disconnect=true;
          System.out.println("Matched else");

      }

    }
    server.close();

First of all, the client sends an "h" packet, and expects the same back (handshake). However, I want it to disconnect the client when an unrecognised packet is received. For some reason, it responds fine to the handshake and HTML status request, but the else clause is never executed when there's an unknown packet.

Thanks
