You can tack it on as a header after the Response.ok()

return Response.ok()
    .entity(json.toString())
    .header("Access-Control-Allow-Origin", "*")
    .header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT")
    .build();

Or do it in an implementation of ContainerResponseFilter and register that filter to your application.

Probably don't want to leave it as * unless you want user's browsers from other sites accessing your API though.
