From the initial email it seemed as though it's a two stage process
(stage 1 : generate, stage 2 : export), hence I thought it possible that
an idle time out could occur during the generation phase.
One approach I've seen is that a servlet starts the generation and lets
the user carry on with their interaction with the webapp. Once the
generation is complete the user is emailed a link where they can
download the generated file. All this would, of course, need the
necessary security put over the top to ensure users didn't download each
others files.

If the timeout occurs during the PDF generation, before the response
begins being streamed back, maybe. But as long as there is response
data being transmitted, no timeout should occur at the connection
level. A session timeout is an app-server function, anyhow; clients
and proxies know nothing about the session.
Simon, is the timeout occuring during the request for the PDF, while
it is being generated and before the action begins transmitting it? Or
is the PDF downloaded successfully with the next request failing
because the session timed out during the download?

If the file takes so long to generate is there any reason why your
not pre-generating it, caching it and serving it as a static file?

Subject: Request/session timeout when exporting very large files
Hi,
I'm having this request/session timeout problem.
My page have a link to generate and export pdf file. The problem is
sometimes the generated file is very huge (100MB++) and it takes
quite some time to export it (30 to 90 minutes). How do I prevent it
from timeout when it is exporting at that time?
I tried session.setMaxInactiveInterval() but it's not working.
Thx.
