Writing FOP output to BLOB

Question

Hi Experts !
i am using Apache FOP to generate PDF from xml. I am able to generate PDF file from the xml by using fol code :-
public void convertXML2PDF(File xmlfile, File xsltfile, File pdffile)
throws IOException, TransformerException {
     //OutputStream pdfout = null;
     try {
// configure fopFactory as desired
FopFactory fopFactory = FopFactory.newInstance();
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
// configure foUserAgent as desired
// Setup output
OutputStream out = new java.io.FileOutputStream(pdffile);
out = new java.io.BufferedOutputStream(out);
try {
// Construct fop with desired output format
Fop fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, out);
// Setup XSLT
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(xsltfile));
// Set the value of a <param> in the stylesheet
transformer.setParameter("versionParam", "2.0");
// Setup input for XSLT transformation
Source src = new StreamSource(xmlfile);
// Resulting SAX events (the generated FO) must be piped through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
transformer.transform(src, res);
} finally {
out.close();
System.out.println("Success!");
} catch (Exception e) {
e.printStackTrace(System.err);
System.exit(-1);
this code writes the output to a file on disk. I am required to write the output to BLOB as File IO is not an option. Can someone please help me out in directing the outputstream to BLOB with no file IO.
Best Regards !

Use PreparedStatement.setBlob(int, java.io.InputStream) (with a PipedInputStream/PipedOutputStream pair if you can't get an InputStream from FOP?).
