/**
 * DispatchMDBMessageListenerImpl supports dispatching of calls to a
 * Stateless Session Bean.
 *
 * DispatchMDBMessageListenerImpl is intended to be used as the <ejb-class> of
 * the <message-driven> bean in the resource adaptor's deployment descriptor
 * (ra.xml).  When it is used, the <messaging-type> should be set to
 * org.apache.cxf.jca.inbound.DispatchMDBMessageListener.  Also, the resource
 * adaptor's deployment descriptor should specify the same interface
 * (org.apache.cxf.jca.inbound.DispatchMDBMessageListener) in the
 * <messagelistener-type> in order to activate the inbound facade endpoint.
 * Since the Message Driven Bean is used to activate the inbound
 * endpoint facade by CXF JCA connector, all the required resources (such as,
 * service endpoint interface class, WSDL, or bus configuration) should be put
 * in the same jar with the Message Driven Bean.
