The Response Layer

The response layer is responsible for "responding" to the execution. The responses are handled by invoking an appropriate sender defined on the receiver's response information. Each sender defined in the system knows how to process its response. For example:

The JMS queue sender and the JMS topic sender post responses to the appropriate queue / topic.
The staging control sender handles errors received during the execution of the staging control request.
The upload staging sender updates the status of the upload staging record based on the success or failure of the staging upload request.
The download staging sender is a bit unusual because it is helping to build the message being sent (Oracle Customer Care and Billing only).

Note: There are some cases where a response is not applicable. For example, the file scan receiver creates a staging control record to process a file that exists in a directory. There is no "response" applicable for executing this request.
