/**
* Designates a JavaBean as an ActivationSpec. This annotation may
* be placed on a JavaBean. Eventhough the JavaBean is annotated with the Activation annotation
* it is still required to implement the {@link ActivationSpec ActivationSpec}
* interface.
*
* The ActivationSpec JavaBean contains the configuration information pertaining
* to inbound connectivity from an EIS instance. A resource adapter capable of
* message delivery to message endpoints must provide a JavaBean class
* implementing the {@link ActivationSpec ActivationSpec} interface which may be annotated
* with the Activation annotation for each supported
* endpoint message listener type.
*
*
The ActivationSpec JavaBean has a set of configurable properties specific to
* the messaging style and the message provider.
*
*
Together with the messageListener annotation element, this annotation
* specifies information about a specific message listener type supported by the
* messaging resource adapter.
