After spending the day trying to get this to work, I'm finally giving up.
I first had troubles getting jersey to recognize my Provider and it didn't work until I used the web.xml init-param, com.sun.jersey.config.property.packages, to register the package that contained our rest service and the provider. Only then did jersey recognize my Provider.
Once I got jersey to recognize my Provider I experimented with JSONConfiguration. I first tried
new JSONJAXBContext(JSONConfiguration.natural().build(), types);
And that worked, but it unfortunately produced an unnamed array in JSON. I then added the rootWrapping(false)
new JSONJAXBContext(JSONConfiguration.natural().rootUnwrapping(false).build(), types);
That worked for XML, but produced a runtime exception for JSON

SEVERE: null
org.codehaus.jackson.JsonGenerationException: Can not write a field name, expecting a value
This appears to be an outstanding issue with Jersey:
http://jersey.576304.n2.nabble.com/Root-Unwrapping-configuration-for-JSON-representation-in-Jersey-1-1-5-td4613395.html#a5544087
I am using jersey 1.2 and see the issue. So I've spent a day on this and am giving up. Personally I think it's a bug in jersey.
