Displaying Byte Array images in coldfusion

Question

This has been driving me crazy for a couple of days now.I
have a Java class that returns pictures stored in a DB as a Byte
Array.
I am able to display the image but that is all i am able to
do - I want to display the image name, description etc in a HTML
before i display the actual image but i can't seem to find a way to
do that.
I tried using CFcontent as well and that did not help
either.This is what i am currently doing - and all that displays on
the screen is the picture and all content before the picture is
nowhere to be seen.
Picture Name: #variables.picName#
Picture Description:#variables.picDescription#
<cfscript>
context = getPageContext();
response = context.getResponse().getResponse();
out = response.getOutputStream();
response.setContentType("image/jpeg");
response.setContentLength(arrayLen(session.picture));
out.write(session.picture);
out.flush();
out.close();
</cfscript>
Any help will be greatly appreciated.

Mark,
Note that the portal sets the content type (e.g, text/html) and encoding
as the portal page starts rendering. In your case, the
setContentType() would be useless since the servlet container won't let
you change it. You can either use a popup browser window for the pdf as
Kunal suggested, or use an iframe if you want to render the pdf inside
the portlet window.

Hi,
i need to display a PDF file. The PDF is stored in a byte array. This works fine when i run my code (see below) from the .jpf via the debugger/browser, but when i use it as a portlet, in the portal, it does not work ?
Any help is much appreciated.
Thanks

byte[] pdfDocument = docStore.getPDF();
ServletOutputStream outPdf = response.getOutputStream();
response.setContentType("application/pdf");
outPdf.write(pdfDocument);
outPdf.flush();
outPdf.close();
