Jboss 6 & problem with timerService in singleton
Hi
I have a problem with my singleton.
It looks like this :
@Singleton
@Startup
@Local(StartupService.class)
public class StartupServiceBean implements StartupService {
(...)
@PostConstruct
public void init() {
ScheduleExpression schexp = new ScheduleExpression();
schexp.second("30");
schexp.minute("*");
schexp.hour("*");
timerService.createCalendarTimer(schexp);
And i have exception:
23:49:40,500 ERROR [org.jboss.ejb3.timerservice.mk2.task.TimerTask] Error during retyring timeout for timer: [id=aff4f3f6-a604-4786-9f36-839e23b09857 timedObjectId=jboss.j2ee:ear=com.komisarski.letter.ear-1.0.ear,jar=com.komisarski.lette

But when i changed @PostConstruct to @Schedule(second="*/10", minute="*",hour="*", persistent=true)
everything is working fine. So i believe, that during startup of a singleton bean jboss is not ready yet to persist timer (it's only my theory)
But why ? And how i can avoid these exceptions ?
