[JBoss-user] scheduling in JBoss

[G.L. Grobe]

Looking for anyone who has implemented a scheduler of any sort in their J2EE apps?   My application is layed out on JBoss 3.0.1 as ...   Velocity pages -> Webwork Servlets -> EJB's   Problem is I'm not sure where to put a scheduler in this mix. Some jobs are triggered on demand from the user (no problem here). Other jobs that are stored in the database (like cron tasks) need to be triggered, I'm guessing by an external scheduling server. I'd then like the job progress information from that external scheduler server to be viewed by the users (which means communicate back to the JBoss server).   In otherwords, I'd rather not have the complexities of an external app to have to trigger and communicate back and forth to JBoss if I don't have to ... but I don't see how to get around it since ejb's don't seem to be a good place for this to happen. Be nice to keep it all in one package.   I hope that was clear, any ideas/thoughts much appreciated.
