title: Server not responding
body: <p>I'm making a server/client application in Java but it doesn't really work the way I want it to.</p>
  
  <p>I make a connection and everything goes fine but then it does nothing. I'm thinking it doesn't come to my thread for accepting the client.</p>
  
  <p>Here's my code.</p>
  
  <p>Networking Thread:</p>
  
  <pre><code>package libgdx.server;

  public class NetworkingThread extends Thread {
  private Socket sock= null;
   private int ID;
  
  public NetworkingThread(Socket sock){
      super("Multiple connection thread!");
  
      this.sock = sock;
  
   }
  
  @Override
  public void run()  {
     try{
     System.out.println("In the Method run() in the thread!");
  
         PrintWriter out = new PrintWriter(sock.getOutputStream(),true);
  
      BufferedReader in = new BufferedReader(new InputStreamReader(sock.getInputStream()));
      String inputLine,outputLine;
      AlphaProtocol alpha = new AlphaProtocol();
      outputLine = alpha.ProcessInput(null);
      out.println(outputLine);
  
      out.println("Welcome to the Server! Hope you enjoy your stay.");
      while ((inputLine  = in.readLine()) != null){
          outputLine = alpha.ProcessInput(inputLine);
          out.println(outputLine);
          if (outputLine.equals("Bye!")){
              break;
          }
      }
      out.close();
      in.close();
     sock.close();
     }catch(IOException ioe){
         ioe.printStackTrace();
         System.err.println("Error in the Tread of Connecting and Method Run()");
     }
  
  }

  <p>This is the tread on the server for accepting clients and handling them :)</p>

  <p>When I run the application,</p>
  
  <p>I get this:</p>
  
  <pre><code>   Client:    Hello, welcome to LibGDX Network test: #1 
     Type the server ip in:
     127.0.0.1 // My INPUT!
     Type the server port in:
     4444  // My INPUT!
     IP:127.0.0.1Port:4444
  </code></pre>
  
  <p>And the server:</p>
  
  <pre><code>Server listening!
  Networking!
  Networking!
  Networking!
  Networking!
  Networking!
  Networking!
  Networking!
  </code></pre>
  
  <p>It just prints "Networking!".</p>
  
  <p>Any help would be appreciated!</p>
