java - RMI 应用程序在从终端运行时抛出错误，但在 Eclipse 中工作正常

Question

我正在尝试使用 java RMI 开发一个聊天应用程序，多个客户端可以在其中相互交互。问题是，代码至少到目前为止在 Eclipse 中运行良好，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，它抛出一长串 ChatServer_stub.class ClassNotFoundException。 ChatServer_stub.class 在那里，我的意思是我无法在不使用 rmic 创建 stub 的情况下启动服务器。有任何想法吗？？？我不认为这个问题与代码有任何关系，因为它与 Eclipse 一起工作，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

我想答案就在这里:http://docs.oracle.com/javase/6/docs/technotes/guides/rmi/codebase.html

在这篇文章中发现了类似的问题，并有一个很好解释的解决方案: running rmi server, classnotfound
