How to do it...

1. Let's create a User class as a model for our JSON message:

public class User {    private String name;    private String email;    public User(){            }    public User(String name, String email) {        this.name = name;        this.email = email;    }    @Override    public String toString() {        return "User{" + "name=" + name + ", email=" + email + '}';    }    //DON'T FORGET THE GETTERS AND SETTERS    //THIS RECIPE WON'T WORK WITHOUT THEM}

2. Then, let's create a class to use JSON-B to transform an object:

public class JsonBUser {        public static void main(String[] args) throws Exception {        User user = new User("Elder", "[e-mail]");                Jsonb jb = JsonbBuilder.create();        String jsonUser = jb.toJson(user);        User u = jb.fromJson(jsonUser, User.class);         jb.close(); ...
