RE: Scheduler
I agree, leave all the web specific stuff out of it. I wrote a little program that ran on a timer and broke it down into two simple classes. One class does the actual work, the other class wraps the first one and implements the Struts Plug-In and Runnable interfaces. Simple, easy. Putting the business logic into a non-web related object makes it reusable and malleable. The wrapper class is simply used as an invocation mechanism by the web container that calls the first object (which is the real program). I don't think I could have made it any simpler. http://www.c2.com/cgi/wiki?DoTheSimplestThingThatCouldPossiblyWork -Original Message- From: EL AKARI Mehdi [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 02, 2003 9:07 AM To: Struts Users Mailing List Subject: Re: Scheduler Hi all, In my opinion, an application that should do the job you specified has nothing to do with struts.

Yeah that is what we ended up doing, wrapping Quartz in a JMX bean. We had a consultant come in and convert half our system into JMX beans.

Re: Scheduler
Hi Gurpreet I haven't tried this...but it came across my mind as I need something similar very soon. You could write a Struts plugin... init() method called on start of webapp and destroy() method called on shutdown of webapp. In the init() method you could start a thread that "wakes up" at specified interval, say each minute, to check if there is some tasks that need to be done, eg sending mails, cleaning up, make some coffee (;-)) In the destroy method you could stop the thread again I don't know if this violates with the J2EE spec...I remember reading something about threads...but that might be for EJBs only...Anyone can shed some light on this issue? Regards Henrik - Original Message - From: "Gurpreet Dhanoa" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Tuesday, December 02, 2003 12:47 PM Subject: Scheduler hi All I want to implement a scheduler program something at the starting of the application or at the starting of tomcat. Basically i need one of my program to track all of the reminders i have set in an web-application. Say if i have set a reminder to send an email to client at 1400 hrs then it should send that email at that time without the need of signing into the account. Any help will be of great use.
