Why OSGi at JavaBlackBelt.com ?

You'll get most more abstract definitions on the officical website (http://osgi.org) but in short they describe it as "OSGi technology is the dynamic module system for Java".

Infact, OSGi Core is a dense & concise about 288 pages specification. It is well known as the vehicle of eclipse (since 3.0) as well as a (somtimes disliked by some people) more sophisticated and proven JSR 277 (Java Module System - hint: just speaking of the module-layer of osgi)

More companies are considering OSGi as a platform just because more and more framework implementations are getting stable. To name the most prominent ones:

• http://felix.apache.org
• http://www.eclipse.org/equinox/
• http://www.knopflerfish.org/
• http://concierge.sourceforge.net/

as well as a growing toolchain that makes life a lot easier. Here are some you should know about if you think of going into osgi:
