Flying Saucer's primary purpose is to render spec-compliant XHTML and CSS 2.1 to the screen as a Swing component. Though it was originally intended for embedding markup into desktop applications (things like the iTunes Music Store), Flying Saucer has been extended work with iText as well. This makes it very easy to render XHTML to PDFs, as well as to images and to the screen. Flying Saucer requires Java 1.4 or higher.

I have ended up using ABCPdf from webSupergoo. It works really well and for about $350 it has saved me hours and hours based on your comments above.

Use itext libray:

Here is the sample code. It is working perfectly fine:

String htmlFilePath = filePath + ".html";
String pdfFilePath = filePath + ".pdf";

// create an html file on given file path
Writer unicodeFileWriter = new OutputStreamWriter(new FileOutputStream(htmlFilePath), "UTF-8");
unicodeFileWriter.write(document.toString());
unicodeFileWriter.close();

ConverterProperties properties = new ConverterProperties();
properties.setCharset("UTF-8");
if (url.contains(".kr") || url.contains(".tw") || url.contains(".cn") || url.contains(".jp")) {
    properties.setFontProvider(new DefaultFontProvider(false, false, true));
}

// convert the html file to pdf file.
HtmlConverter.convertToPdf(new File(htmlFilePath), new File(pdfFilePath), properties);

When I needed HTML to PDF conversion earlier this year, I tried the trial of Winnovative HTML to PDF converter (I think ExpertPDF is the same product, too). It worked great so we bought a license at that company. I don't go into it too in depth after that.
