Hi, I have been working on a few small enhancements, some of them are complete and some need more work. I would like to check in the following changes into some 4.x or 5.x release if we agree that the changes are good: 1. new HAPartition methods for calling a specific cluster targetNode (identified with opaque server reference that is currently a org.jgroups.stack.IpAddress). This was useful for sending messages to a specific target node in the cluster. 2. A load balancing policy based on FirstAvailable that always favors a same machine choice. 3. A load balancing policy that always picks the ha-singleton server (depends on ha-jndi and a server side ha-singleton). The hapartition ehancement is minor and easy. The other changes are additions so they shouldn't break anything. I have a ejb enhancement as well but I'll post about that in ejb design forum. Thoughts?
