This talk discusses a return upon experience in the refactoring of the JOnAS Java EE core that proposes a flexible and dynamically adaptable services layer. Relying on an OSGi based architecture, the application server is improved in several aspects such as modularity, dynamism, code loading and unloading, on demand server adaptation, re-configuration, services update on the fly.

This talk starts with a brief introduction of the OSGi concepts, an overview of the expected benefits for JOnAS and the pros and cons that the new Service Oriented Architecture offers. Based on the experience gained with JOnAS, the refactoring process of a first class Java EE enterprise application server is discussed afterwards,: dependencies management, new defined modules, project build tools, continuous testing, OSGi specifics. Indeed, JOnAS 5, based on Apache Felix, illustrates perfectly the unification between OSGi and the Java EE world.
