Service is built using interface-based programming model. To be determinedbuild a service one must basically provide implementation of a interface. To consume, one only need the interface for the lookup and there is no need to know about the implementation.Before starting working at your lab, please take a look at an example of services implemented in the book [http://equinoxosgi.org/ OSGi and Equinox, Creating Highly Modular Java Systems]  |criteria=To be determined}}
