Java Docx4J错误[Content_Types].xml与WebLogic 12c

我想知道是否有人在安装过程中遇到过同样的问题：

WebLogic12C

Docx4J 2.8.1

Java EE 6

我试图使用Docx4J获取某个Microsoft Word 2007文档的内容，但出现如下错误：

当我尝试这样做时：

WordprocessingMLPackage package = WordprocessingMLPackage.load(new File((path));

它将抛出如下异常：

正如Docx4J论坛中所建议的，但没有任何用处

也没有答案

Java 6应该在内部有自己的JAXB实现，但到目前为止，我已经尝试了：

没有在库中放置任何jaxb jar

将jaxb jar放在2.1.7、2.2.4和2.2.6版本上，两者都不起作用

---

另外，如果它有任何帮助的话，如果我从void main运行它，同样的方法也会起作用，如果它是从WebLogic服务器执行的，那么它就不起作用，因此我确信存在类加载问题。

要让docx4j与WebLogic 12c一起工作，据说您可以升级eclipselink，或者切换到JAXB参考实现

要升级Eclipselink，请参阅

无论如何，现在切换到JAXB RI是一种更好的方法

---

请注意，要在docx4j中使用Eclipselink JAXB实现，您应该使用docx4j 3 beta版或更高版本。

如果是类加载问题，您可能需要设置应用程序加载它们的顺序。退房：
