Yes we're using dynamic lookup in the JAX-RS resource.
But maybe your idea makes things just even better, so we should add it to
Robert's list. I just was curious to understand it's inner sense, but we can
discuss that later. Possibly I just don't see the big trick with it.

Ok, understood. Sounds like the same thing that is getting discussed
currently on Jersey's user list (don't know if you followed it). As our
architecture currently is split into a JAX-RS facade and EJB SLSB backend
(and since we had no trouble with that) I just wasn't so deeply into the
ideo of consolidating both. But I understand that this could be beneficial
in some scenarios.
The question is how this could be made possible. Maybe you already have a
discussion paper in your desk to add to Roberto's tracker item?
