Vladyslav, thanks for tha link. That is exactly what I am looking for. The problem is that we are planning to go in production in 2 weeks on JBoss 3.2.1 and the service seems to be implemented in JBoss 3.2.2. Do you have the source code to the mentioned "HASingletonController" and the "HASingletonMBeanExample"? I could use that and implement the solution I suggested just that the SingletonController activates or deactivate the scheduler on the master instance.
Thanks a lot. --Marcus > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Vladyslav Kosulin > Sent: Tuesday, August 12, 2003 9:27 PM > To: [EMAIL PROTECTED] > Subject: Re: [JBoss-dev] Cluster aware Scheduler > > > Look at > http://www.cocoonhive.org/articles/jboss/20030610/hasingleton.html > > Marcus Redeker wrote: > > > All, > > > > I am looking for a cluster aware scheduler service.
