I notice that quite a bit of the failover logic has ended up in the ClusteredConnectionFactoryDelegate class. The idea with the client aop stack is all the logic - including the failover logic should be in a set of aspects and the actual delegate classes should be as dumb and thin as possible. So this logic should really be in a FailoverAspect, or something similar. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3988896#...
