Java chat program giving me Connection Refused [duplicate]

问题

I am trying to build a java chat program. I have 7 classes for server and client altogether.

My errors are as follows when I run any class

    Exception in thread "main" java.rmi.ConnectException: Connection refused to host: 192.168.56.1; nested exception is: 
java.net.ConnectException: Connection refused: connect

... 7 more

Here is my ChatServerDriver class

   import java.net.MalformedURLException;
   import java.rmi.Naming;
   import java.rmi.RemoteException;


   public class ChatServerDriver {

public static void main(String[] args) throws RemoteException, MalformedURLException{

    Naming.rebind("RMIChatServer", new ChatServer());

}

}
