Thank you for the fast reply! And sorry - I though that I have to use JbossMQ... I have found some related topics: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104294#... http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104715#... I'm not sure yet if I'll need to preserve the order in case of one consumer for some queue. But I want a cluster just for the failover. I want all my producers and consumers connected to one node - the master one, the slave is just to replace it in case of failure. Also I think that all the messaging will work faster if there is no pulling of messages from one node to another. Can you tell me where can I find this FAQ of how to configure JBM as a ha-singleton?
