無法初始化類org.apache.xerces.jaxp.datatype.xmlgregoriancalendar

Question

我正在使用Web服務（爲組件定製服務）來發送和接收信息。請求正在形成，我也得到了迴應。然而，應對實際DTO的映射過程中，我收到以下錯誤：

could not initialize class org.apache.xerces.jaxp.datatype.xmlgregoriancalendar 

中有一些與響應calednar日期的形式，但我不知道，爲什麼它不能初始化xmlgregoriancalendar類。我用我的本地存根運行它，它根本不會給我帶來任何問題。

任何adivse將是有益的...在此先感謝

完整的堆棧跟蹤如下：

Answer 1

我也得到了這個錯誤：NoClassDefFoundError: Could not initialize class org.apache.xerces.jaxp.datatype.XMLGregorianCalendarImpl

這是我如何修復它。在weblogic.xml中添加以下行：

{prefer-web-inf-classes}true{/prefer-web-inf-classes} 

默認情況下它是false。

此修復程序告訴我存在jar版本衝突。但我不知道在哪個文件夾中導致衝突的具體罐子。
