Poblems injecting EntityManager in an annotated Jersey resource
Hi,
I've been investigating using injected EntityManager into jersey resources
to get context managed transactions. I've gotten it to work with Glassfish 3
but have failed to get it working with OpenEJB which I would prefer to be
using.
The jersey issue http://java.net/jira/browse/JERSEY-230 describes both a
preferred implementation and a fix done for Glassfish 1,5 years ago (fix
might be relevant?). I've implemented a resource called PersonResource as
desribed in the issue with a persistance unit called "testunit" and it works
with Glassfish 3.0.1 (I can successfully make a transaction using the
injected EntityManager), but with Tomcat 6/OpenEJB 3.1.3 I get a null
reference for the EntityManager i.e it doesn't seem to be injected. The
OpenEJB log indicates that things get initialized correctly (?) at
deployment:

I'm guessing a different implementation using separate classes for the bean
and resource might work but I'm not really sure how to do that and would
prefer the implementation as is described in
http://java.net/jira/browse/JERSEY-230

I've managed to track down the Glassfish revision that fixed the problem
there, hoping that might help someone that knows more than me about this
stuff :) :
http://java.net/projects/glassfish/sources/svn/revision/25742 (the note
"Added interceptor registration spi to enable jax-rs injection into EJB
components implemented as resources")
