It is true, but what I was thinking about was something similar to Spring OSGi context declaration, which allows you to declare beans, OSGi services and import them from the context of one module bundle to another.
Here the import seems easy using JEE dependency injection and annotations, but you still have to declare bundle activator and register your services in code, not in config file. I was wandering whether or not such way of bundle services declaration (one XML config file) is supported by JEE and whether or not it is possible to avoid declaring them in code.
BTW. great video tutorial, clarifies a lot!
