Assume a server supports a set of HTTP driven applications - a browser or a soap client of some sort - that are all coming through a sticky load balancer. I assume a single JNDI tree so that all of the nodes in our cluster have the same world view so to speak. Is that assumption correct? A second question is what happens when you have a set of unrelated application server clusters or external applications using the same data database? Specifially what is the impact on cluster A when records are adding or removing through cluster B? Is this a pencil-eye issue (mom, it hurts when I stick this pencil in my eye:)?
