这种情况是在Web应用程序中引发的，但在一个独立的应用程序中不会发生这种情况。任何想法，我使用docx4j 3.3.0。
运行Jboss 6.3的应用程序。
在使用旧版本（3.2.2）之前，但不会抛出此错误。

答案 0 :(得分：1)
看起来您正在转换为PDF。
根据http://www.docx4java.org/forums/announces/docx4j-3-3-0-released-t2381.html发行说明在v3.3.x中发生了变化：
默认PDF转换器已从XSL FO + Apache FOP更改为Plutext＆＃39 商业PDF转换器。基于XSL FO的PDF输出移至 新的/单独的项目docx4j-export-fo;之后我们做了这个改变 仔细考虑，因为质量/性能是如此之多 更好，它从docx4j本身删除各种依赖项。如果你 想要坚持现有的XSL FO + Apache FOP PDF转换，没有 probs： - 见下文。
使用converter-eval.plutext.com上的PDF Converter实例 默认，但您可以（并且应该！）在本地安装它;安装人员 可在http://converter-eval.plutext.com/
获取要使用您自己的实例，请设置docx4j属性，例如：
com.plutext.converter.URL = http://converter-eval.plutext.com:80/v1/00000000-0000-0000-0000-000000000000/convert
如果您想使用现有的XSL FO + Apache FOP PDF转换， 只需将docx4j-export-fo（+ deps）添加到您的类路径中。如果是这样的话 目前，docx4j将恢复为基于FO的转换。这些罐子是 在zip文件中，在dir optional / export-fo和Maven Central中。
使用默认PDF转换器（即商业版）时，您需要相关的docx4j 3.x依赖项，在本例中为https://github.com/plutext/docx4j/blob/master/pom.xml#L502
