CQ does not support using Apache CXF to expose a service so other external clients can invoke it (either a Restful or Soap service). That is - you cannot create a CQ WSDL or Restful service.
Only internal clients (ie - a JSP) can invoke a service. CQ does support using Apache CXF to write a service that consumes external services (ie - a 3rd party WSDL). For anyone reading this thread and want to know how to use CXF to write a service to consume a 3rd party soap stack -- see:

If this is functionality that you really need -- i suggest that you file a ticket here:
