All Implemented Interfaces:

LoadBalancePolicy

public class FirstAvailable
extends AbstractLoadBalancePolicy

LoadBalancingPolicy implementation that always favor the first available target i.e. no load balancing occurs. Nevertheless, the first target is randomly selected. This does not mean that fail-over will not occur if the first epr in the list dies. In this case, fail-over will occur, and a new epr will become the first member and invocation will continously be invoked on the same new epr until its death. Code based on jbossas ha framework.
