Upgrading to Jackson 2.0 from 1.9 in Jersey not working

Question

I\'m using Jackson (in Jersey) to serialize entities, and I\'m migrating from Jackson 1.9 to 2.0. I followed this guide, and at first it seemed like everything worked out ea

Answer 1

I'm answering my own question, based on the (useful) answers from StaxMan and pgelinas.

I had to do two things to make it work.

The first things was to remove the com.sun.jersey.api.json.POJOMappingFeature from my web.xml.

The second was to update my jackson-jaxrs-json-provider (actually, all of my Jackson artifacts) to 2.1.

With 2.1 or 2.0, and POJOMappingFeature, Jackson 1.9 was still being used for serialization.

With 2.0, and POJOMappingFeature removed, I got a missing message body writer error.

With 2.1 and POJOMappingFeature removed, everything worked as expected.
