Question

我第一次使用RMI Connection在Java SWING中编写程序。我已经为客户端导出了JAR并且工作得很好但是当我试图打开一个特定的JFrame /窗口时，它什么也没做，我收到以下错误消息

我的程序使用JDateChooser打开的Jframe / Window，我认为这是问题所在。我不需要改变，所以JFrame打开了。当我运行Eclipse中的程序没有这个错误消息。它工作得非常好。与Build Path有关？

Answer 1

您缺少包含com.toedter.calendar.JDateChooser（可能是jcalendar-1.X.jar）的Jar文件。
你可以创造一个＆＃34;胖＆＃34; jar使用eclipse或将你的Jar依赖项添加到执行类路径中，如提到here 一种选择是使用Fat Jar Eclipse Plug-In，另一种选择是使用Maven创建它，如提到here。

使用JDateChooser导出Jar错误
