I have a EJB cluster setup in JBoss 6.3.0 EAP with many (remote) clients talking to those EJB nodes. I'd like to be able to deploy or restart nodes in my EJB cluster without service disruption. Currently, if you shutdown a jboss node that is in the jgroup for the ejb cluster, any clients with remote EJB calls to that node will see errors. I'd like to be able to tell a node to shutdown and have any currently running EJB requests process while rejecting new requests. In a web tier, this would happen in some sort of load balancer. Is this possible today for a EJB cluster? Would this be some sort of enhancement for the remoting3 implementation?
