使用JEuclid在PDF（XSL-FO）中生成公式

Question

I am trying to transform an xml to pdf which contains formulas. I have added jeuclid jars to handle formula. Whole xml is transformed properly except the formulas. I am getting blank where there are formulas.

public class PDFCreation {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        PDFCreation pdfCreation = new PDFCreation();
        try {
            pdfCreation.convertToPDF("SPE.xsl", "IPTC-19048-MS.xml", "IPTC-19048-MS.pdf");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void convertToPDF(String xsl, String xml, String pdf) throws IOException, FOPException, TransformerException {
        File xsltFile = new File(xsl);
        StreamSource xmlSource = new StreamSource(new File(xml));
        FopFactory fopFactory = FopFactory.newInstance(new File(".").toURI());
        FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
        OutputStream out;
        out = new java.io.FileOutputStream(pdf);
        try {
            Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
            TransformerFactory factory = TransformerFactory.newInstance();
            Transformer transformer = factory.newTransformer(new StreamSource(xsltFile));
            Result res = new SAXResult(fop.getDefaultHandler());
            transformer.transform(xmlSource, res);
        } finally {
            out.close();
        }
    }
}

EDIT: As requested adding console log

I have not written anything for formula in my xsl as I read JEuclid handles it.

Do you have the mathml namespace on your fo:root tag? Like so:

<fo:root xmlns: fo="http://www.w3.org/1999/XSL/Format" xmlns:mathml="http://www.w3.org/1998/Math/MathML">
