Carlos Sierra commented on ARIES-1784:
--------------------------------------
Hey [~jalbert],
it is in the JAX-RS 2.1 specification, Section 2.1:
{{The resources and providers that make up a JAX-RS application are configured
via an application-supplied subclass of Application. An implementation MAY
provide alternate mechanisms for locating resource classes and providers (e.g.
runtime class scanning) but use of Application is the only portable means of
configuration.}}
The whiteboard is just handling the provided service to the JAX-RS
implementation, CXF in this case.
Carlos.
