Java docx4j2.8.0.jar无法使用grail工作

我整天都在用我的应用程序运行grails测试运行应用程序，一切正常。我键入“grails prod war”以获得一个war，并将其部署在我的linux操作系统的Jboss 6.0中。使用docx4j.jar的WordprocessingMLPackage.load（inputStream）方法读取docx文件时，我发现错误：

WordprocessingMLPackage inputMLPackage=WordprocessingMLPackage.load（inputStream）

若我尝试使用DynamicWebProject做同样的事情，那个么并没有错误。这是什么原因？因为我的web inf库中有docx4j jar

谢谢
