Are you sure that your webserver or application server is not timing out?
I know that apache and JRun have timeout settings - maybe your setup does
too.
Hope that gives you a possible lead.

Subject: Browser time-out
When user logs into HTTP servlet, the login activity takes 3 minutes
(accesses a database, etc.). Unfortunately, the browser times out at 2
minutes. My Web app server doesn't support response streaming
(PrintWriter.flush has no effect), and I'm not sure if that would prevent
the timeout anyway.
I'm considering the following. Any easier alternatives?
- Servlet recognizes it will take awhile to process request
- Servlet returns HTML with "Please wait..." page with "<meta
http-equiv=\"Refresh\"content=\"60\">" to cause browser to ask again in 60
seconds.
- Before doGet completes, servlet kicks off lengthy processing on another
thread. Call it dbAccess thread.
- doGet completes
- Processing continues on dbAccess thread.
- 60 seconds later, browser sends refresh request - same URL, same parms
- Servlet associates with original request and issues Object.wait until the
dbAccess thread issues Object.notifyAll.
- Servlet returns page
- Both threads (doGet and dbAccess) are now done.
