我正在使用Web服务（为组件定制/定制服务）来发送和接收信息。请求正在形成，我也得到了答复。但是，在将响应映射到实际DTO期间，我收到以下错误：
could not initialize class org.apache.xerces.jaxp.datatype.xmlgregoriancalendar
响应中有一些calednar日期表单，但我不确定，为什么它无法初始化xmlgregoriancalendar类。我在我的本地使用存根运行它，它根本没有给我任何问题。
任何adivse都会有所帮助......提前致谢

答案 0 :(得分：1)
我也遇到了这个错误：NoClassDefFoundError: Could not initialize class org.apache.xerces.jaxp.datatype.XMLGregorianCalendarImpl
以下是我修复它的方法。在weblogic.xml中添加以下行：
{prefer-web-inf-classes}true{/prefer-web-inf-classes}
默认情况下，它是假的。
此修复程序告诉我存在jar版本冲突。但我不知道究竟是哪个文件夹中的哪个罐子会导致冲突。
