Using JEuclid to generate formula in PDF(XSL-FO)

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 get any warning messages in the console log? Also, consider including a short example of FO file with a simple formula, for others to try and provide you precise help. — lfurini
You can have a look at the resulting FO file calling FOP from the command line with the -foout option: fop -xml IPTC-19048-MS.xml -xsl SPE.xsl -foout output.fo (or using your xslt processor of choice to perform the transformation). This way you can check wheter there is actually some MathML in it or not, as the warning messages you are getting seem unrelated to the problem. — lfurini

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">
