@rickyzen, that link has nothing to do with converting to PDF !?

@roy_sanu,

The problem is that there is no direct link between xml/xsl and pdf. What you will most likely need to do, is do the XSL transformation to HTML as you are doing now, and then add an additional step to render the HTML to a PDF document.

A quick Google search gives the following options,

 - iText
 - Flying Saucer (uses iText internally but may provide useful extensions)

Note however, that because these will be using different rendering engines to what any of the normal browsers use, the output could well look different to what you see in a browser (just like how different browsers show some pages slightly differently)

In case you get stuck, using iText and XMLWorker (I used the 5.4.1 versions from Maven)

http://itextpdf.com/download.php

...and with this code, it is made quite easy (you may want to play around with the styles, as iText will be different to what you normally see in a browser)
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.StringReader;
import java.io.StringWriter;

import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerFactoryConfigurationError;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;

public class ConvertXMLtoPDF {
    
    public static void main(String[] args) throws TransformerFactoryConfigurationError, TransformerException, DocumentException, IOException {
        Transformer transformer = TransformerFactory.newInstance().newTransformer(new StreamSource(new File("transform.xsl")));
        StringWriter writer = new StringWriter();
        transformer.transform(new StreamSource(new File("input.xml")), new StreamResult(writer));
        
        Document document = new Document();
        PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
        document.open();
        XMLWorkerHelper.getInstance().parseXHtml(pdfWriter, document, new StringReader(writer.toString()));
        document.close();
    }
}
