Great posts! I got some questions though. Why deploy the singleton sar on all nodes and not place it in /farm directory on one node as Ivanov describes in his article? And finally, isnt possible instead of using the RMI adaptor to use the HA_JNDI cluster wide tree? I mean MBeanServer is ofc no option. Can we use the HA-Jndi here and if yes could you give me a tip how? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962116#...
