[jboss-user] [JBoss Seam] - using raiseTimedEvent / TimerSchedule
I couldn't find a working example on the forums, so now I've got one, I thought
I'd do the right thing and post.
Note:
1. I'm using a POJO here, and didn't change my components.xml at all. If I was in
a EJB component, I guess I could have used the EJB (or quartz?) timer service, but what I
have here is all I needed.
2. Seam 2.0 and JBoss 4.2.2.
3. The event stuff in Seam is great. Thanks Seam people!
