Docx4j 转换为 pdf 时抛出异常

Question

此异常是在 Web 应用程序中引发的，但在独立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 eap 的应用程序。

在使用旧版本 (3.2.2) 但未引发此错误之前。

Answer 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 的发行说明，v3.3.x 中发生了一些变化：

默认 PDF 转换器从 XSL FO + Apache FOP 更改为 Plutext 的 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；我们做了这个改变之后 仔细考虑，因为质量/性能是如此之多 更好，它从 docx4j 本身中删除了各种依赖项。如果你 想坚持现有的 XSL FO + Apache FOP PDF 转换，没有 问题：- 见下文。

converter-eval.plutext.com 上的 PDF Converter 实例由 默认，但您可以（并且应该！）在本地安装它；安装程序是 可在http://converter-eval.plutext.com/

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

如果要使用现有的 XSL FO + Apache FOP PDF 转换， 只需将 docx4j-export-fo (+ deps) 添加到您的类路径中。如果这些是 目前，docx4j 将恢复为基于 FO 的转换。这些罐子是 在 zip 文件、dir optional/export-fo 以及 Maven Central 中。

使用默认的PDF Converter（即商业版）时，需要相关的docx4j 3.x依赖，在本例中为https://github.com/plutext/docx4j/blob/master/pom.xml#L502
