We are using some JSON-B annotations to customize our user data representation:

    @JsonbProperty("fullName")
    private String name;

The @JsonbProperty is used to change the field name to some other value:

    @JsonbTransient
    private Double privateNumber;

Use @JsonbTransient when you want to prevent some property appearing at the JSON representation:

    @JsonbDateFormat(JsonbDateFormat.DEFAULT_LOCALE)
    private Date dateCreated;

With @JsonbDateFormat, you use the API to automatically format your dates.

And then we use our UI manager to update the view:

    public void loadUser(){
        long now = System.currentTimeMillis();
        User user = new User(now, 
                "User" + now, 
                "user" + now + "@eldermoraes.com",
                Math.random(),
                new Date());
        
        Jsonb jb = JsonbBuilder.create();
        json = jb.toJson(user);
    }
