you should call the setContentType() and whatever the ...size() method is on the response object, rather than writing that to the output stream. *THEN* write the bytes out.

I think you're missing the bigger concept. A PDF is the same as a JPG - it's a media file that differs from just the plain text sent in an html page.
You can't just stream a PDF in the middle of HTML. You have to associate it with a content type, and the browser has to make a request for it, just like it does for images. One HTML page with 2 images == 3 requests to the server: 1 for the text, 1 for each image. Browsers (generally) won't make a request for a PDF embedded in the page, as there is not related tag (like the img= for gif/jpg).
So, if your user gets to your stored PDF by clicking a link, your rendering JSP page might look like this:
<myTag:showPdf pdfid="123"/>
your tag would then: - output the Content-Type and (ideally) filesize to the datastream - then write out the bytes of the PDF file to the datastream - end the tag
the browser will handle everything else
out.println("Content-Type=.......
byte[] pdf = loadPdf(123);
// write the bytes to out in whichever manner is most efficient

And then what? I can easily access it from the form bean field and from the session. There's no problem here. The question is how to stream it to the client. Please see my previous email.

JSP is the same as Servlet. Put your pdf content in the session scope, you can get it on your jsp page through session.getAttribute("pdfContent");

I know the best way to do it is to have a servlet. But I need to do it in a JSP because of certain limitations of my application. Please help.
Thanks.
