Re: Running a heartbeat program in struts.
Keep this in mind. What do you do if the http connection is down for longer than 5,10,15 minutes? Receiving lots of email with the same message can be very anoying. -D - Original Message - From: Ron Day [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Saturday, February 01, 2003 9:46 PM Subject: Running a heartbeat program in struts.

It will only send email once, and set a flag. Flag will be reset when http connection comes up again. But thanks for the comment.
