A related question to this is, how can you set up a process within the servlet that fires off at X time, or every Y seconds? The equivalent of a cron job inside the servlet.
If you have high enough traffic, there's an easy hack - just store a Date object as a servlet-level attribute, and check on each request if the current time is greater than or equal. But is there a cleaner solution? Also, it would be nice to have a little more precise control than hoping that a user will happen to come to the site at the right time. I suppose you could spin off a thread that sleeps for X amount of time, wakes to check on the situation, and goes back to sleep when done. To the specific question - I would guess (incorrectly?) that there's no Java file system listener. But I could certainly be wrong... ?
