This is an overview how to build an OSGI EJB3 Server I gave at OSGIExpertsDay at JAX09.
The Server is build using:
Eclipse Equinox as OSGI Framework
Eclipse Riena for Remote OSGI Services
EasyBeans as OSGI EJB3 Container
Hibernate as JPA Provider
Clients are Rich Clients (Eclipse RCP)
The project is model-driven using UML (MagicDraw), EMF (Eclipse Modeling) and oAW (openArchitectureWare).
