We have a remote web service, a thick client will invoke this web service
to run a long report on server side and get the report back, which takes
a while, say, several minutes.
Unfortunately, the connection will be reset before the report is returned
and
a broken pipeline error would show up on server side. I guess some hardware
in between detects there's no activity after certin period and resets it.
Is there any simple way to get around this?

I think that is basically no way. At best you could try and see if
different client (telnet, java, browser) would make a difference.
One possible approach is to return dummy result (or the job id) first.
Then on the subsequent query (with job id) check if the job has been
done or not.

when using http, one normal create a timer on the html
and refresh the page once a while until the report is generated.
i guess similiar approach can be done on your case.

browser may have time out setting. if that is the case, you can ask your
clients to change their browser setting. for example, as i know, IE uses
registry to control time out, but you can change the time out time.
if the timeout happens on the server side, you need to check the timeout
configuration for each intermediate node. For example, apcahe web server can
be timed out, firewall can be timed out, etc. It is my understanding that
you can always configure the time out time no matter how many
clients to change their browser setting. for example, as i know, IE uses
registry to control time out, but you can change the time out time.

Since it's a web service, you have a lot of flexibility.
The server can just return a key (job id) in the response
and start a thread to do the job. The client then polls job
status with the job ID.

I think the same way.
But I don't know how to store the real result on server before client
retrieve. (I only know DB solution)

A temp dir named with the session ID would be good.
Delete the result dir after client retrieves it.
A thread or cron job to "maintain" that directory: remove
expired results.

That's my first reaction too, except the client needs to initiate
the connection with keep alive, which is what a modern browser
would do these days.
But if it takes several minutes for most requests, I'd redesign
it to use the asynchronous model others already suggested.

We had exact problem in one previous project. Since
our client displays the result list in pages, it was
natural for us to use pagination and ask the results
page by page.

It's more work than loading a simple page but there's
probably no way around that.

If a job takes longer time, it can not be solved with
pagination. You can still refresh and refresh, until
the page gets the result, though.
