you need to set up the content-type header. The data you're getting back is the PDF, but the browser doesn't know it's a PDF. – HocusPocus

You might want to add one header where you mention response is an attachment ->

response.addHeader("Content-Disposition", "attachment; filename=" + pdfFileName);

ByteArrayOutputStream baos = // make a bytearray output from the document
// setting some response headers
response.setHeader("Expires", "0");
response.setHeader("Cache-Control", "must-revalidate, post-check=0, pre-check=0");
response.setHeader("Pragma", "public");
response.setHeader("Content-Disposition", "attachment; filename=filename.pdf");
// setting the content type
response.setContentType("application/pdf");
response.setContentLength(baos.size());
BufferedOutputStream bos = new BufferedOutputStream(response.getOutputStream());

baos.writeTo(bos);
bos.flush(); 
bos.close();
