我正在使用 docx4j 2.8.1 并尝试转换几个不同的 docx 文件，但我总是遇到同样的问题。问题可能来自库的版本或缺少某些依赖项。

代码：

package test;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;

import org.docx4j.convert.out.pdf.PdfConversion;
import org.docx4j.convert.out.pdf.viaXSLFO.PdfSettings;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;


public class pdfConverter {
    public static void main(String[] args) {
        createPDF();
    }

    private static void createPDF() {
        try {

            // 1) Load DOCX into WordprocessingMLPackage
            InputStream is = new FileInputStream(
                    new File("D:/TestDoc/Res.docx"));
            WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage
                    .load(is);

            // 2) Prepare Pdf settings
            PdfSettings pdfSettings = new PdfSettings();

            // 3) Convert WordprocessingMLPackage to Pdf
            OutputStream out = new FileOutputStream(new File(
                    "D:/TestDoc/Res.pdf"));
            PdfConversion converter = new org.docx4j.convert.out.pdf.viaXSLFO.Conversion(
                    wordMLPackage);
            converter.output(out, pdfSettings);

        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

}

错误：

通过更换罐子解决。我用的是 2.8.0，现在很好。
