How do you create a PDF from XML in Java?

Question

At the moment, I\'m creating an XML file in Java and displaying it in a JSP page by transforming it with XSL/XSLT. Now I need to take that XML file and display the same info

Answer 1

You can apply XSL-Fo to your XML and transform it with Java transformer:

File xmlfile = new File(baseDir, xml);
File xsltfile = new File(baseDir, xsl);
File pdffile = new File(outDir, "ResultXMLPDF.pdf");

FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();

OutputStream out = new java.io.FileOutputStream(pdffile);
out = new java.io.BufferedOutputStream(out);

try
{
    Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
    // Setup XSLT
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer transformer = factory.newTransformer(new StreamSource(xsltfile));

    transformer.setParameter("versionParam", "1.0");

    Source src = new StreamSource(xmlfile);

    Result res = new SAXResult(fop.getDefaultHandler());

    transformer.transform(src, res);

} finally {
    out.close();
}

System.out.println("Success!");
