I would say a <receive> alone is a service if it represents a one-way operation in the BPEL composition. <receive> can also be accompanied with a corresponding <reply> in which case both of them put together is a service. A subset of activities ( and a combination of activities) are services based on the way they serve clients. -- Pranam _____________________________________________________________________ Pranam Kolari Department of Computer Science University of Maryland, Baltimore County Baltimore, MD 21250 Contact: (Work) +1 410 455 3971 :---: (Home) +1 410 536 4772 kolari1@cs.umbc.edu :---: http://www.cs.umbc.edu/~kolari1 _____________________________________________________________________
