Calling OSGI Services from a Jaggery App

There can be situations where a Service exposed as an OSGI component needed to be called directly from a Jaggery app, without exposing the srvice as a RESTful service. This is pretty simple and all it takes is the following snippet. 
var carbon = require('carbon'); var datasetService = carbon.server.osgiService('');
where "" is the full class path of the class exposed as the OSGI service. Then any method in the service can simply be called as follows.
