{Ecl_menu}<h2>OSGi Services</h2>
:A bundles can register and use services in OSGi. OSGi provides therefore a central registry for this purpose. A service is defined by a Java interface (POJI - Plain Old Java Interface) [http://www.vogella.de/articles/OSGi/article.html#OSGiintro_services].
:Access to the service registry is performed via the class [http://www.osgi.org/javadoc/r4v42/org/osgi/framework/BundleContext.html BundleContext]. OSGi injects the BundleContext into each bundle during the startup of the bundle. A bundle can also register itself to the BundleContext [http://www.osgi.org/javadoc/r4v42/org/osgi/framework/ServiceEvent.html ServiceEvents] which are for example triggered if a new service is installed or de-installed.
