我想知道是否有人在安装时遇到了同样的问题：
WebLogic 12c
Docx4J 2.8.1
Java EE 6
我试图通过Docx4J获取某个Microsoft Word 2007文档的内容，但是出现了如下错误：
当我尝试做时：
WordprocessingMLPackage package = WordprocessingMLPackage.load(new File((path));
它将引发异常，如：

如上所述，我正在使用JDK 6，所以这本来是不可能的消息。
但是上面的消息在内部被Docx4J抑制，而是引发以下异常：

Docx4J论坛中建议使用I tried this，但没有用。
This question也不会给出答案。
Java 6应该在内部具有它自己的JAXB实现，但是到目前为止，我已经尝试过：
不要在库中放入任何jaxb jar
放置jaxb jar版本：2.1.7、2.2.4和2.2.6，均无效。
另外，如果有什么帮助，如果我从void main运行它，同样的方法也可以工作，但是如果它是从WebLogic服务器执行的，则它就不起作用，因此我确信存在类加载问题。
最佳答案
据报道，要使docx4j与Weblogic 12c一起使用，您可以升级eclipselink，或切换到JAXB参考实现。
要升级Eclipselink，请参见http://www.docx4java.org/forums/weblogic-f25/how-to-update-to-eclipselink-2-5-in-web-t1574.html
http://www.docx4java.org/forums/weblogic-f25/classcastexception-in-weblogic-12c-t1643.html#p5675建议，就目前而言，切换到JAXB RI是更好的方法。
请注意，要将Eclipselink JAXB实现与docx4j一起使用，应使用docx4j 3 beta或更高版本。
