Re: How to set orion to perform a timely task.. (CRON???)
One way is to write a simple Java program that uses URLConnection to hit your JSP page and have CRON drive your simple program. tim. > Someone suggesting hitting a JSP with a cron... how can you hit a URL with > a CRON or AT command, I didn't think you could do that!

RE: How to set orion to perform a timely task..
Title: SV: How to set orion to perform a timely task.. First of all, there is an option to load a servlet at startup so that you don't need to wait for the first request comes in. Secondly I prefer this way better. You could create a separate ejb client application to start your timer daemon thread and package with your ear file. Then configure your orion-application.xml to start your embeded ejb application at start-up.

Could you explain me the servlet solution with a Timer, please ? The point that I do not undestand is following: On one hand, the servlet cannot stay loaded forever, probably the server will detect and unload unused servlets.On the other hand, in order to activate a servlet, the server has to receive an HTTP request to the tcp/ip port that server is listening to, therefore the Timer should implemente a tcp/ip socket. So, how can I wake up my servlet without having to write a socket ? Thanks for explanations, Yves Bossel

Re: How to set orion to perform a timely task..
I think, the most clean approach would be to have a cron job which starts an EJB client every time. Bye, Falk - Original Message - From: <[EMAIL PROTECTED]> > I need to have my EJB perform some DB operation at midnight everyday. > How do I do that?
RE: How to set orion to perform a timely task..
Or you could start a daemon thread in a servlet to perform as cron; we do that to initialize services we need.
