We already have a JOnAS 4 prototype that use OSGi. But I don't know the 
current state of the prototype ... Mikael ?

Yes
Mikael has done a prototype of JOnAS working on top of OSGi.
JOnAS Services are packaged as OSGi bundles, and services are "binded" 
together using OSGI Service Trading (which is not done in the Geronimo 
prototype AFAIK).
Maybe he can tell some words here to complete ?

For now, Geronimo only repackaged their services as Bundles. They don't 
use other OSGi cababilities (Service Trading, ...).

As Takoua said, we aim to use both OSGi and Fractal in JOnAS 5. This is 
not a vs issue but more a cooperation :)
