Message endpoint deployment
Before any messages can be delivered to a message endpoint, the message endpoint must be associated with a destination. The responsibility of associating a message-driven bean with a destination lies with the application deployer.
The application deployer creates an instance of the ActivationSpec JavaBean for the relevant resource adapter and associates it with the message endpoint during installation. In this way, an ActivationSpec JavaBean, through its destination property, associates a message endpoint with a destination on the message provider.
