Java聊天程序给我连接被拒绝

Question

我正在尝试构建一个java聊天程序。我总共有 7 个服务器和客户端类。

当我运行任何课程时，我的错误如下

    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

这是我的聊天服务器驱动程序类

   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());
}

}
