The OSGi Alliance - Open Services Gateway initiative - is an open standards organization founded in March 1999 that originally specified and continues to maintain the OSGi standard. OSGi technology seems to be remarkably difficult to those unfamiliar with it.
Definition
OSGi enables the development of applications from components that could be
- reusable
- dynamically composed
- hide their implementation
- communicate their dependencies and services
- Bundle is the name for a component in the OSGi Architecture.
- Bundle is the name for a component in the OSGi Architecture.
