public abstract class RMIServiceRequester
extends ServiceRequester

This abstract class is used for Requesters willing to use RMI communication with Providers. Note: a Requester is not required to use any particular communication API, this class is models one type of communication but it is the programmer's responsibility to pick up the right communication model for his service. As long as the concrete service requester extends the ServiceRequester class the RelateGateways system will handle and export it correctly.
