Dan,
http://blogs.sun.com/arungupta/entry/totd_124_using_cdi_jpa is an
example that shows how DAO can be injected in a JAX-WS or JAX-RS class.
Few differences from your example ...
- DAO interface and impl are the same class
- Everything is bundled together in a WAR file
- No EJB module
I'll try your packaging style but can you look through the above blog
and see if something is missing.
Thanks,
-Arun
