/**
* DispatchMDBInvoker is executed in the context of a Message Driven Bean
* that dispatches calls to the target Session Bean where the service logic is
* implemented. The target must be a Stateless Session Bean. Since

* Message Driven Bean must be configured to include a local reference to
* the target bean in the deployment descriptor. The advantage of using
* DispatchMDBInvoker is that no modification to the resource adapter's
* deployment descriptor (ra.xml) is required to add or remove inbound endpoints.
