We are using jboss-4.2.3.GA with Jboss ESB 4.4-GA, Jboss Messaging 1.4.2-GA. also We have different types of datasources defined : a) In section "6.2 : Target Jboss DS to oracle" , We are using xa-datasource. b) In section "8.2 Juddi" we are using local-tx-datasource. c) "8.3 Service Bus" has local-tx-datasource. d) "8.4 JBpm" has xa-datasource. I am not sure if this is right? Should we using same type of datasources at all the places for HA? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4212368#...
