Greetings,
I have a particularly thorny problem that I REALLY need help for. Anybody
that even has a few vague ideas about a possible solution, PLEASE get in
touch with me.
Here's the problem:
I have a servlet that generates a PDF file based on form data. The purpose
is to display the PDF in the client browser and let the client use the
browser print function to print the PDF. All of that works fine. Recently
added functionality, tho, demands that the client be able to select multiple
forms, generate one huge PDF with all the forms as a page in the PDF, and
print that, without ever having to see the actual PDF. (ie ... client can
choose one form, in which case the PDF pops up on his screen and he can then
do what he likes with it ... OR client can choose multiple forms, in which
case they just go straight to his printer). Now .. generating the PDF is no
problem ... the problem is what to do with it THEN. The plan is to generate
PDF files in batches of 100 pages each (so if they select ALL on a 2500 form
database, they get 25 PDF file) .... a 100 page PDF file is approximately 1
megabyte. I can write it out to a file on the server, or to any kind of
stream.
SO ... how do I get the PDF from the server to the client printer??? This
is driving me nuts, I can't figure it out at ALL, PLEASE HELP!!!
Another (much less satisfactory) option would be to send some sort of stream
to the client browser such that they download the generated PDF files and
then do what they want with them from there. Outside of just displaying it
all in the browser, how do I do THAT???
I'm trying to avoid having to save the generated PDF to the server, as this
is expected to be a fairly high volume web site, and if I go saving 1 meg
files all over the place, it'll chew through the hard drive in no time flat.
SO ... ANY clues at all would be MUCH appreciated!!!! Thanks in advance.
