My preference would be to send a jms message to an MDB and return to the browser with a page that does a meta-refresh to keep checking if there is a "reply" message. This gets you out of the server so that it can service other requests between "checks". Ultimately, it should scale better than tying up the servlet thread for "long running" operations. It also has the advantage that the mdb can potentially be on another machine, again, for scalability.

Subject: (New subscriber) "Busy Page"
Hi,
Sorry if this has been covered before - I couldn't see anything in the
archive.
What I want to know is the best/preferred way to display a "Busy"
page/message while my servlet grinds away crunching numbers.
At the end to the processing I want my html report output to be
displayed
instead of the "Busy" message.
I've tried lots of ways of doing this (redirects/imports via JSPs,
ServletFilters
etc) but nothing ever does the very task I required. Surely this is a
very
common task.
The only thing I've not bothered trying is firing off a separate thread
to
do my processing. I figure there has to be a cleaner way.
Thanks in advance.
Chris
