如何在Eclipse IDE中用JAVA运行RMI聊天应用程序

我正在用Java开发一个RMI聊天应用程序。我试图在EclipseIDE中运行简单的RMI应用程序。但它存在以下问题。我知道如何在命令提示符下运行它，而且运行起来没有任何问题。如果您能建议我在EclipseIDE中运行RMI应用程序的方法，我将不胜感激。谢谢大家!

错误：

对不起。我不确定这是对还是错。因为我没有在RMI上工作

应用程序。但我相信下面的链接可以解决您的问题

错误清楚地显示“ClassNotFound”。原因：java.lang.ClassNotFoundException:examples.credit.CreditChecker。检查该类是否在您的类路径中可用。@kshitij，谢谢。那么，您能告诉我如何配置类路径吗。此外，我还按照错误中的建议创建了代码基路径。如果这个类在jar文件中，那么您只需要将这个jar文件添加到eclipse项目的lib文件夹中。若它是由您创建的类，那个么您只需要将它放在eclipse项目的src文件夹中@kshitij，它不在jar文件中，因为我正在eclipse的src文件夹中开发它。我指定了以下代码库，它表示无法加载主类-Djava.rmi.server.codebase=${workspace\u loc:/RMIChatServer/bin/}
