The base class will handle the final creation of a reply Message from any of those starting points. If the return value is null, the Message flow will end here.

Specified by:

handleRequestMessage in class AbstractReplyProducingMessageHandler

Parameters:

requestMessage - The request message.

Returns:

The result of handling the message, or null.
