我正在尝试开发一个聊天应用程序,使用javarmi,多个客户端可以相互交互。问题是,至少到目前为止,这些代码在eclipse中运行得很好,但是当我使用rmic之后的标准过程从终端尝试时,启动rmiregistry并启动server,然后启动client,它抛出了一长串chatserver\u stub.class classnotfoundexception。chatserver\u stub.class在那里,我的意思是我不能在不使用rmic创建stub的情况下启动服务器。有什么想法吗???我不认为这个问题与代码有关,因为它与eclipse一起工作,所以我将错误粘贴在这里。以防万一……代码如下:https://github.com/kumarsaurabh20/programming_test/tree/master/network_prog_java/rmichatapp/src

注册表的类路径上没有存根。要么启动注册表,使它这样做,或使用代码库功能。

我猜答案就在这里:http://docs.oracle.com/javase/6/docs/technotes/guides/rmi/codebase.html
在这篇文章中发现了一个类似的问题,并给出了一个解释良好的解决方案:运行rmi服务器,classnotfound
