Yes, although i like to say the POJOs are plugable :-) the compile
time thing is some tooling sugar so the developers don't have to re-
declare the root resources.

Yes, but for different root paths it requires that you extend the
generic RDBMS wraper class and those extended classes have the
UriTemplate annotated on them.

Ah, i see. We have been looking at such things like Java Persistence
API related classes can be injected (via the Resource annotation).
Such injection type stuff is part of EE 5 and we need to see what we
should support in this respect. We have also been looking out how
injection of Java Persistence API stuff could work for non EE
containers too. This definitely requires further discussion.
