Java聊天程序给我连接被拒绝 [英] Java chat program giving me Connection Refused

问题描述

我正在尝试构建Java聊天程序。我总共有7个针对服务器和客户端的类。

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

运行任何类时我的错误如下

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:

... 7 more

这是我的ChatServerDriver类

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());

}

}
