我想知道是否有人对设置有同样的问题：
- 网络逻辑 12c
- Docx4J 2.8.1
- Java EE 6
我尝试使用 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));
它会抛出异常，如：

如上所述，我使用的是 JDK 6，所以这应该是不可能的消息。但是上面的消息被 Docx4J 内部抑制，而是抛出以下异常：

我按照 Docx4J 论坛中的建议尝试了这个，但没有用。
这个问题也没有答案。
Java 6 应该在内部拥有自己的 JAXB 实现，但到目前为止我已经尝试过：
- 不将任何 jaxb jar 放入库中
- 放置版本的 jaxb jar：2.1.7、2.2.4、2.2.6，都不起作用。
此外，如果它有任何帮助，如果我从 void main 运行它，同样的方法也有效，如果它是从 WebLogic 服务器执行的，它就不起作用，所以我确信存在类加载问题。
