is it possible to get a hand on the pdf in question?

With the following code :
private static String pdfImgsToXml() throws IOException {
int pageNumber = 1;
String imgs = "<imgs>\n";
PDFRenderer renderer = new PDFRenderer(pdf);
int numPages = pdf.getNumberOfPages();
for (int i = 0; i < numPages; i++) {
imgs = imgs + "<img" + pageNumber + ">";
try {
BufferedImage image = renderer.renderImageWithDPI(i, 200);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write( image, "jpg", baos );
baos.flush();
byte[] imageInByte = baos.toByteArray();
baos.close();
String imgString = Base64.encode(imageInByte);
imgs = imgs + imgString + "</img" + pageNumber + ">\n";
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
pageNumber++;
}
return imgs + "</imgs>";
}
My app is running on a Java EE Server, trying to write rendered images to
byte array to put them in XML.
But first I need to render them, and that's not working.
Thanks,
Pierre
