business process bpmn implementation with services in uddi

Dear everyone,

could anyone provide me the link to the tutorial of implemenation bpmn with service in uddi?
I don’t know how can i call a service, and how i implement a service in bpmn process with jdeveloper.

many thanks in advance,

For the link to the tutorial, I will update you.
But I think you can expose or call a service as a web service provider/consumer in your bpmn,as we do have an option to call a webservice in bpmn.
