Re: [JBoss-user] (Code Example -- LONG) Timer MBan Problem
Hi,
so far so bad. What kind of interface do I have to implement?
Is there an example of EJBs using the timer-MBean service???
Help?

Here's an example that works for me. YMMV. I've tried to remove all
application specific code, but still leave relavent timer MBean code. I
reset the timer on each timer call. You can probably set the timer up to
send periodically. The timerInterval is in seconds in this example
(default
10 seconds). Blame formatting stuff on VisualAge :).
Good luck!

Hi all,
Could someone send me a Timer MBean sample?
Thank you in advance.
