Apache Felix is an open source implementation of the OSGi Release 4 core framework specification.[1] The initial codebase was donated from the Oscar project at ObjectWeb.[2] The developers have worked on Felix for a full year and have made various improvements while retaining footprint and performance. In June 21 2007, the project graduated from incubation as top level project and considered the smallest size software at Apache Software Foundation.

Running Felix
To run Apache Felix OSGi you need to download the felix-framework-2.x.x.tar.gz or felix-framework-2.x.x.zip compressed file from the site.[3] Once you have extracted the Felix framework distribution, from the command line in the extracted directory type the following:
java -jar bin/felix.jar
After that, bundles are installed running and typing command like help from the console will display all available commands, which are:
bundlelevel <level> <id> ... | <id> - set or get bundle start level. cd [<base-URL>] - change or display base URL. find <bundle-name> - display bundles matching substring. headers [<id> ...] - display bundle header properties. help - display impl commands. inspect - inspect dependency information (e.g., packages, service, etc.). install <URL> [<URL> ...] - install bundle(s). log [<max>] [error|warn|info|debug] - list recent log entries. obr help - OSGi bundle repository. ps [-l | -s | -u] - list installed bundles. refresh [<id> ...] - refresh packages. resolve [<id> ...] - attempt to resolve the specified bundles. shutdown - shutdown framework. start <id> [<id> <URL> ...] - start bundle(s). startlevel [<level>] - get or set framework start level. stop <id> [<id> ...] - stop bundle(s). sysprop [-r] [<key>] [<value>] - Display, set, modify and remove system properties. uninstall <id> [<id> ...] - uninstall bundle(s). update <id> [<URL>] - update bundle. version - display version of framework.
