17 Overview of OSGi Technology Operation Framework Manage bundles Framework can install, update, and uninstall Bundles Bundles can be started and stopped Provides a method to share services Supports a package sharing Bundle A Jar file containing Java Classes Manifest with information about bundle Can also cat like a DLL (shared library) Bundle states Installed/Uninstalled Resolved Starting/Stopping Active KRnet

18 Bundle State Transitions KRnet

19 The Framework Install A Framework start Bundle A { } Events: install Bundle B { } Events: register Bundle C { } KRnet

20 The Framework uninstall stop Events: uninstall Bundle A { } Framework Bundle B { } Events: unregister Bundle C { } KRnet

21 Dependency Management When a bundle is stopped, it is cleaned up Registered services are removed References to other services removed Bundles can be notified when a service they depend on is unregistered Class path dependencies are managed Model will allow long running applications with dynamic software updates KRnet

22 Installing a Bundle Check bundle is not already installed using location String 1) InstallBundle (locationstring) Bundle context Framework Bundle A ( Java class, Html file, manifest file Etc.) 2) Obtain bundle s contents (location or inputstream) Allocate associated resources( bundle unique identifier, storage area etc..) A Bundle Object INSTALLED KRnet
