  • OSGi:http://www.osgi.org/Main/HomePageOSGi(open service gateway initiative) technology is Universal Middleware. OSGi technology provides a service-oriented, component-based environment for developers These capabilities greatly increase the value of a wide range of computers and devices that use the Java platform.
