Answer 1

Check if you are registering the media type for JSON support. Do you have jersey-media-moxy on your class-path? If not, add this dependency to your pom.xml, please check your jersey version, in this example I'm using Jersey 2 (2.24)

    
        org.glassfish.jersey.media
        jersey-media-moxy
        2.24
