Hi Gabo

Please send me a copy...

Unfortunately it is not possible to have multiple root resource classes with the same Path value. Actually, it is possible, but JAX-RS specs says that after the first root class has been selected it is this resource only that the runtime continues working with, others are not checked.
We've discussed a couple of times the idea of extending the implementation such that if the first matching resource has no matching operation then then next matching one, if any, is tried next.

cheers, Sergey

HTML WADL view will also be done/available later on and it will make the whole WADL instance more readable, I was thinking to utilize Mark Nottingham's stylesheet but then I looked at it again and decided to step back and may be come up with something CXF-specific.

I haven't done it yet, but I am seriously planning to. But is it
possible to have two classes to have the same path annotation? I am
thinking of having two services with no path annotations (which as you
said defaults to "/")

I was thinking the "/Service/operation" of class2 should also be
included since the path would still match and this would be similar to
the result of actually invoking the said service.
