I ran into some other odd problems opening documents so I also added in
addition to those below to correct them:
response.setHeader("Pragma", "public");

Hi Michael,
Thanks for your reply. My original code was correct,
and it was basically the same as yours in terms of the
steps. I think the important steps are
setContentType(), and setContentLength().
I was getting a blank page because of my IE version
(6.0.2800.1106), it requires me to add the following
to see the pdf:
response.setHeader("Cache-Control", "must-revalidate,
post-check=0, pre-check=0");
after hours of tweaking and trial and error I stumbled
on the workaround by accident.
