Hello I am migrating to jboss 4.0.4 from 4.0.2. I have a few Singletons deployed on my partition. According to the JBoss 4.0.4 release notes: "ScheduleProviders are now cluster unaware, in terms of class dependencies. To make them behave as cluster singletons, simply configure a dependency on jboss.ha:service=HASingletonDeployer,type=Barrier." I have done this change. The hosts on the Partition correctly detect each other. The services are executing only on one machine. The problem arises if I stop the service on the active node. The service isn't starting on the other node. The Singleton only starts if I completely stop the master jboss. This was working correctly on previous versions of Jboss. Can any one help me please? Thanks in advance. Regards, Victor Batista View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3968989#...
