Getting Started with OSGi on GlassFish
By pelegri on Jul 28, 2008
Now that almost all the app servers - except Geronimo? - are providing extensibility via OSGi, we all need at the least some basic knowledge on it so check out Arun's Deploying on GFv3 and Geertjan OSGi in GlassFish in 5 steps.
Direct user programming on OSGi is less universally adopted. On the server-side JavaEE 6 will support extensibility and modularity. And, on the client side (one rev farther on the OpenJDK Modules project) there is the proposal for Supporting OSGi Bundles in the Java Module System and Mandy's recent blogs on: OSGi Repository for Java Module System and Support for the module keyword.
Added Just noticed Johan's note on Running GFv3 on KnopflerFish.
