Apache Felix is an open source implementation of the OSGi Release 5 core framework specification.[1] The initial codebase was donated from the Oscar project at ObjectWeb.[2] The developers worked on Felix for a full year and have made various improvements while retaining the original footprint and performance. On June 21, 2007, the project graduated from incubation as a top level project and is considered the smallest size software at Apache Software Foundation.

Running Felix
Lua error in package.lua at line 80: module 'strict' not found. To run Apache Felix OSGi, you need to download the felix-framework-4.x.x.tar.gz or felix-framework-4.x.x.zip compressed file from the site. 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 bundles are installed and running, typing a 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.
