Answer 1

To use Jackson 2.x as your JSON provider you need to add jersey-media-json-jackson module to your pom.xml file:

    org.glassfish.jersey.media
    jersey-media-json-jackson
    2.22.2

And then register the JacksonFeature in your Application/ResourceConfig subclass.

For more details, have a look at Jersey documentation.
