We are using JMS IDs for sequencing, so if we have 2 nodes in JBoss JMS cluster setup, then because the way JMS ID generation is implemented for JBoss Msg 1.2 (each node gets a block of JMS IDs), the sequence will be lost if 2 nodes process requests in parallel. To avoid this scenario and still to have an automated failover, i am looking into it. Either way it will be good to know if there is an option to deploy Active/Passive way.
