/**
 * JMS implementation of ArchivedPagePublisher.
 * Intended usage is to notify other VMs that a pageDTO needs to be
 * evicted from cache.   This occurs when the page is marked as
 * archived - typically because a replacemet page has been
 * promoted to production.
 *
 * Utilizes Spring JMS template pattern where template and destination
 * are configured via Spring.
 *
 * Created by bpolster.
