[jboss-user] [EJB 3.0 Users] - Execute TimerService().createTimer() exactly once in a clust

First off, I've read the article at: http://www.jboss.org/community/wiki/DeployingEJB3TimersInCluster I now have a SLSB with an @Timeout which is deployed with: <depends>jboss.ha:service=HASingletonDeployer,type=Barrier</depends>
The problem is, unlike the article linked above, I will not be starting the timers multiple times over the lifetime of the application. In my case, I want the timer to be started exactly once for the whole cluster.
I previously had a ServletContextListener subclass where contextInitialized() would kill all timers and start them. The problem is, now if I have more nodes join the cluster, the timers are killed and recreated. Is there a better way to accomplish this?
Additionally, I thought maybe I could start the Timer in the @PostConstruct of the SLSBs themselves. However, this fails with TimerService.getTimers should not be access from this bean method: IN_EJB_CREATE
Any help regarding this is appreciated! Thanks.
