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.

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.

Re[2]: SV: How to set orion to perform a timely task..
If you put the code at the init function, you can force the servlet to load at startup by putting the tag priorityNumber in the servlet description in web.xml. priorityNumber defines the order in which the servlets will be loaded at startup. -- Best regards, Rafaelmailto:[EMAIL PROTECTED]

a simple jsp that activated your functions activated by a cron script (or at on NT) would work great, and you wouldn't have to write a schedler -jesse schoch On Mon, 5 Mar 2001, Magnus Rydin wrote: > how about an client-application that does some operation on scheudled hours? > WR > > > -Ursprungligt meddelande- > > Fran: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > > Skickat: den 3 mars 2001 09:44 > > Till: Orion-Interest > > Amne: How to set orion to perform a timely task.. > > > > > > Hello, > > I need to have my EJB perform some DB operation at midnight everyday. > > How do I do that? > > In PC, I could create a timer object to do that with VC++, but in Java > > it does not seem to have such a functionality.

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.

How to set orion to perform a timely task..
Hello, I need to have my EJB perform some DB operation at midnight everyday. How do I do that? In PC, I could create a timer object to do that with VC++, but in Java it does not seem to have such a functionality. And I think it's ideal to handle it in the server side rather than play with Java. In other words, orion may have such a cron function built in to do something in a timely manner. If anyone has any experience with this, please tell me how. Thank you very much in advance. Simon
