Indeed, it is alwayse good, since all the big application server

My question is : is the today bundle model of Nuxeo framework already
compliant to these soon comming OSGI platform ? Or does it still
need some adaptations ? Maybe it is obvious since the components can
be deployed on equinox, but it is to understand ...
A JAR is OSGi compliant if it contains an OSGi MANIFEST. From this point
of view Nuxeo modules are OSGI compliant bundles.
Now, whether a Nuxeo bundle will run correctly in a standard OSGI
framework is another question.
Nuxeo5 application need some refactoring to be able to run on an OSGi
platform.
So nuxeo bundles as individual artifacts will be loaded correctly in an
OSGi framework.
But the Nuxeo5 application as a whole will not run on an OSGI platform
because some MANIFEST.MF are not 100% correct
(Manifest headers like Export-Packages are not filled - and because of
this classes inside the bundle will not be visible outside)
Anyway these are problems that can be fixed in a few days of work.
Nuxeo already have some bundles that are running on OSGi frameworks like
runtime and core bundles and some of the platform bundles.
All the bundles that are used by Apogee are running correctly on OSGi
frameworks. (Apogee RCP application is based on these bundles)
May be the biggest runtime difference between the JBoss framework and an
OSGi framework is the class loading mechanism which is totally
different.

That's cool, reusing existing OSGi features is always good.
