【问题描述】：
我正在尝试使用 java RMI 开发一个聊天应用程序，其中多个客户端可以相互交互。问题是，代码运行良好，至少到目前为止，在 Eclipse 中，但是当我使用 rmic 之后的标准程序从终端尝试它时，启动 rmiregistry 并启动服务器，然后启动客户端，它会抛出一长串 ChatServer_stub.class ClassNotFoundException。 ChatServer_stub.class 在那里，我的意思是我不能在不使用 rmic 创建存根的情况下启动服务器。有任何想法吗？？？我认为这个问题与代码无关，因为它与 eclipse 一起使用，所以我在这里只粘贴错误。 以防万一..这里是代码：https://github.com/kumarsaurabh20/Programming_Test/tree/master/network_prog_Java/RMIChatApp/src
