[jboss-user] [JBoss Seam] - Modular pluggable components application

I'm trying to build an application platform which all of its layers can be affected by pluggable components,

I assume such a design could be achieved if each component (in my example seam component) can be affected by some kind of external packages,

There are few problems I see around this design,

First of all, I'm not sure if seam can help here, and if there are any assistance for affecting a component behaviors externally,

JavaEE, its packaging design does not support such a model, OSGI model could fit here exactly but I can't see how this is done in jboss without using external platforms, probably archiving a jar per component can partially solve the problem, but I guess these jars must be apart of the application and configuration descriptors must be modified when new components being deployed.

Nuxeo (OSS ecm) created a runtime platform which implements an OSGI model for JavaEE(especially Jboss app server), but I'm trying to find some more natural solution,

Well, I guess this is not only a seam question, but having a discussion about how seam can help in designing such an application could be interesting :-)
