Hello, I have 2 stateful services A and B, which are implemented by singleton MBeans. I also have a JBoss cluster with 2 nodes. MBeans A and B do nothing when they are not in the master node. Is there any way to have the following configuration: Node 1: MBean A acting as "master", Mbean B acting as "slave" Node 2: MBean A acting as "slave", MBean B acting as "master" and if any node fails, the other assumes as "master" for both MBeans? I am thinking of running 2 JBoss instances on each computer, but I would like to know if that is the best solution. Thanks and best regards, Jeronimo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4103105#...
