Sean:
Once I started programming longer tasks with servlets I ran into the same
issue - longer timeouts are one way, but the user only wants to wait so long
in any case. I eventually came up with a method of putting an object name,
method & parameters into a queue table in a database, then having a
server-side task (or more than one) that reads 'em back out, processes the
"job" and emails the user to let them know it's done (or logs the
notification for a later servlet to show to the user). I've bundled all this
into the Expresso open-source framework, so if you'd like an example of it,
grab a copy at our site.
The bottom line is that if I know something is going to take any more than a
few seconds, I just go ahead & queue it - it's something like the JavaSpaces
concept, but a bit more old-fashioned :-)
