title: RMI no such object in table, Server communication error
body: <p>My goal is to create a Distributed computing program that launches a server and client at the same time. I need it to be able to install on a couple of machines and have all the machines communicating with each other, i.e. Master node and 5 slave nodes all from one application.</p>
  
  <p>My problem is that I cannot properly use unicastRef, I'm thinking that it is a problem with launching everything on the same port, is there a better way I am overlooking?</p>
  
  <p>this is part of my code (the part that matters)</p>
  
  <p>try {</p>
  
  <pre><code>        RMIServer obj = new RMIServer();
          obj.start(5225);
  
      } catch (Exception e) {
         e.printStackTrace();
  
      }
  
  
        try {
              System.out.println("We are slave's ");
              Registry rr = LocateRegistry.getRegistry("127.0.0.1", Store.PORT, new RClient());
  
              Call ss = (Call) rr.lookup("FILLER");
  
              System.out.println(ss.getHello());
  
          } catch (Exception e) {
              e.printStackTrace();
          }
  }
  </code></pre>
  
  <p>this is my main class (above)</p>
  
  <p>this is the server class (below)</p>
  
  <p>public RMIServer() {
          }</p>
  
  <pre><code>    public void start(int port) throws Exception {
  
          try {
  
              Registry registry = LocateRegistry.createRegistry(port, new RClient(), new RServer());
  
              Call stuff = new Call();
  
              registry.bind("FILLER", stuff);
  
              System.out.println("Server ready");
          } catch (Exception e) {
              System.err.println("Server exception: " + e.toString());
              e.printStackTrace();
          }
      }
  </code></pre>
  
  <p>I don't know what I am missing or what I am overlooking but the output looks like this.</p>
  
  <p>Listen on 5225
  Listen on 8776
  Server ready
  We are slave's 
  Listen on 8776
