public @interface SendTo

Annotation that indicates a method's return value should be converted to a Message if necessary and sent to the specified destination.

In a typical request/reply scenario, the incoming Message may convey the destination to use for the reply. In that case, that destination should take precedence.

The annotation may also be placed at class-level if the provider supports it to indicate that all related methods should use this destination if none is specified otherwise.
