Hey,
Does OpenEJB 3.1 perhaps support the container manager timers yet? Quintin Beukes |

Right, we have complete support for EJB 3.0 and prior. Timers were
added in EJB 2.x. The new @Schedule annotation of EJB 3.1 is still unimplemented. -David On Oct 14, 2009, at 4:03 AM, Jean-Louis MONTEIRO wrote: > > AFAIK, yes it does. > > Jean-Louis > > > Q Beukes wrote: >> >> Hey, >> >> Does OpenEJB 3.1 perhaps support the container manager timers yet? >> >> Quintin Beukes >> >> > > -- > View this message in context: http://www.nabble.com/TimerService-from-EJB-3.1-tp25873410p25889028.html > Sent from the OpenEJB User mailing list archive at Nabble.com. > > |

That's interesting. I thought timers were 3.1. About 14 months ago I
was looking high/low for a way to schedule routine tasks (hourly/daily/etc - the cron type of things) in my EE app, and everyone the appserver list told me I'd need to use JMX as that's the only option. Timers would have done the trick, even though @Schedule is closer to cron. Thanks.

Well cron style works as well, with an interesting little caveat due to the fact that any timers that went off while the app server were down should be run when restarted during a failure. I'm working on a project around this principal actually, converting a bunch of old perl scripts to something a bit more modern. We ended up using a standalone process w/ openejb and created a scheduler based on the scripts. It works good, but when I start the container all of the jobs kick off, but then resume typical operation.
Ironically, it's exactly what the spec describes to be what should happen. - John -----Original Message----- From: Quintin Beukes [mailto:quintin@...] Sent: Thursday, October 15, 2009 4:06 AM To: users@...

Right, we're definitely open to some contributions there if anyone wanted to take a stab at it. We always have an open door policy regardless, but this area in particular would be a nice spot to dig in. -David |
