java.rmi.ConnectException:拒绝连接到主机：192.168.0.55

我是一个NetBeans和Java的初学者，所以我很确定我的问题是非常基本的，但是在两周的时间里我一直在寻找解决方案，我完全被卡住了

这就是问题所在：

我想实现一个RMI服务器客户端应用程序 所以第一步是尝试使用NetBeans从网络上获得一个工作

我使用oracle教程实现了第一部分

我的问题不是客户端没有连接，而是服务器甚至不能在我给他的端口中注册。错误消息中的IP是我的专用IP

这是我收到的错误消息：

接口如下（非常基本，因为我没有对它做任何操作）

您是否像教程中那样启动RMI注册表？

找到了解决方案。问题出在登记处。在找到它之前必须先创建。简单的解决方案，不知道的时候很难找到。谢谢
