{{Ecl_labs|type=OSGi|description=
In OSGi, a service is a plain java object which is published to a registry. A consumer can consume the registered service through lookup. Service is built using interface-based programming model. To build 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 for the consumer to know about the service 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]
Bring the code from https://guest:1673852@zenit.senecac.on.ca/svn/ecl500/Lectures/trunk/BOOK
into Eclipse and run the ToastClient (read the code).
