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.
Definitions:
OSGi enables the development of applications from components that could be:
- reusable
- dynamically composed
- hide their implementation
- communicate their dependencies and services
- 2. Bundle is the name for a component in the OSGi Architecture.
- 2. Bundle is the name for a component in the OSGi Architecture.
(generic bundle definition - a group of things fastened together for convenient handling[3] )
OSGi Layering The following list contains a short definition of the terms:
- Bundles - Bundles are the OSGi components made by the developers.
- Services - The services layer connects bundles in a dynamic way by offering a publish-find-bind model for plain old Java objects.
- Life-Cycle - The API to install, start, stop, update, and uninstall bundles.
- Modules - The layer that defines how a bundle can import and export code.
- Security - The layer that handles the security aspects.
- Execution Environment - Defines what methods and classes are available in a specific platform.
