Yes, thanks Sergey :) One thing we noticed with Ben's code, is that it tries to use the same old connection factory after failure has occurred. If you're doing the "old style" manual reconnect on failure, you need to throw away the connection factory after failure, or it may not know about the new cluster topology. Also, for this kind of thing, the user code should also bne using HAJNDI to ensure the new JNDI lookup works on a different node after failure of the original node.
