用JDateChooser導出jar錯誤

Question

我第一次用RMI Connection編寫了Java SWING程序。我已經出口了JAR的客戶端和作品真的很好，但是當我米試圖打開一個特定的JFrame /窗口，它沒有做什麼而我會收到以下錯誤消息

JFrame中/窗口，我的程序使用JDateChooser打開，我認爲這是問題。我不知道我必須改變，所以JFrame打開。當我在Eclipse中運行程序時，沒有這個錯誤消息。它的工作非常好。與Build Path有關嗎？

Answer 1

您錯過了包含com.toedter.calendar.JDateChooser（可能是jcalendar-1.X.jar）的Jar文件。
你可以使用eclipse創建一個「fat」jar或者像上面提到的here一樣將你的Jar依賴添加到執行類路徑中。
一種選擇是使用Fat Jar Eclipse Plug-In，另一種是使用Maven創建它，如提到的here。
