Hi Matthew,
For maven users, it is sufficient to add jersey-json module dependency
and set
com.sun.jersey.api.json.POJOMappingFeature
resource config feature (see [1]) to get the desired behaviour.
Jersey currently depends on Jackson version 1.5.5.
Instructions for non-maven users can be found at [2].
HTH,
~Jakub
