Ryan:
OK, with that said, I had always believed that a method annotated with
@PostConstruct would only execute after the injection of an EJB or a
resource?
Or does a method annotated with @PostConstruct - once - run directly
after the Constructor call when the managed bean is initially created?
Thanks,
--Todd

Not in this case. The injection occurs on the actual instance, so the
ctor is always called first.
@PostConstuct is your best bet.
