Hi Ron,What you're doing sounds reasonable enough, provided you're not doing this within an EJB container. If it's just a plain web app. you should be fine. You might want to check out the java.util.Timer class to handle the scheduling and thread management for you; it will also make it easy to have your task run at a specific time each day. Also, you'll want to make sure that the servlet this is coordinated from knows to disable the timer (or interrupt your thread for a graceful stop, if you're not using Timer) when your web app is removed (i.e. in the servlet's destroy method).
Per Walden's recommendation that you do this task outside of the web app... I'd probably do it as a standalone java app. myself (called from the job scheduler) but I don't think there's anything necessarily wrong with your approach either. The hybrid approach using GetURI is an neat idea and worth considering, but I'm not sure you really gain that much for the extra effort.

I have a need for a web application that I'm writing to do a daily check for expiry dates, and if any meet criteria, to email people notifying themof the expiration coming up.I'm currently creating a thread, then making it sleep for 24 hours and run again. Is this efficient to do? Should I be wary of anything by doingthis? Or is there a better way to do it? Ron Power Programmer Information Services City Of St. John's, NL P.O.
