You do have to choose with HTTP: either return HTML or other text, or
return a binary file. No, you can't do both in one response (it's not
like email with attachments and such).
If you take a look at all of the OOTB PDF responses you'll see they
use the Screen Widget and such, but for a purely PDF binary response
and not combined with HTML.
If you want both you can return HTML that has JavaScript in it that
automatically sends a request for the binary file and if you do it
right the effect will be that the user sees the HTML page and shortly
thereafter a download automatically begins.

Hello All:
Can I stream a PDF (from a file within the OFBiz directory) to a
browser without getting a:
java.lang.IllegalStateException: getOutputStream() has already been
called for this response
error?
What I really want to do is stream a PDF file inline with my Screen
Widget/Freemarker Template (so I can re-render the same form,
without request parameters) that the User submitted to initiate the
download. I apologize in advance if this seems like a trivial
question - but I tried several different ways of coding this and
they all come up with this error and (of course) my form still
displays the previously entered request parameters. BTW, I don't get
the error if I set my request-map type="none", but If I do that,
then I can't redisplay the form (which I guess would be obvious to
those who understand how this works :-)

Ruth
