我正在尝试使用docx4j 3.0加载现有的docx文件，进行一些简单的文本更改并另存为PDF。我的代码如下所示：
WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.load (new File (template));
MainDocumentPart doc = wordMLPackage.getMainDocumentPart ();
try
{
VariablePrepare.prepare (wordMLPackage);
}
catch (Exception e)
{
System.err.println ("Warning: VariablePrepare failed: " + e);
}
(here I enumerate all Text nodes and make changes as required)
PdfConversion c = new Conversion (wordMLPackage);
try (FileOutputStream out = new FileOutputStream (outputFile)) {
c.output (out, new PdfSettings ());
}
这将产生以下异常：

任何想法出什么事了吗？
最佳答案
它不应该使用com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
反而org.apache.xalan.processor.TransformerFactoryImpl
（您需要在类路径上使用真正的Xalan）
