i ended up writing a cron-like servlet because as
we migrated code to and from and as the team expanded
we tended to drop/forget the cron (or at) dependencies.
writing a servlet which registered to fire up at server
start time and spun in the backround doing its application
specific task helped ease the appliction deployment cycles
tremendously.
i could try to dig up the code if that'd help. i'm sure
there samples galore out there.
hope this helps,
