Then register that new service chain url into ActorChainRestRegistry.properties, OOTB that already exist and holds the configuration for all the services.
Everything on how to do this is documented at http://docs.oracle.com/cd/E52191_03/Platform.11-1/ATGWSFrameGuide/html/s0502restmvcserviceflowexample01.html
