I am sorry for this time. I was experimenting with
another e-mail client and some messages somehow ended in a wrong folder :o[

It depends on your JAXB beans. To be more specific, if you have:
@XmlElement List<User> user;
then you will end with <user/> tag in XML and
you should add("user").
It really depends on what XML tag name you are dealing with
as a wrapping tag for your array/list.
I am going to announce another JSON notation this week, where
you will get rid of this kind of this a bit complex configuration.
More details will come, but you can try out now with JSONJAXBContext.JSONNotation.NATURAL
and you do not need to bother with configuring anything.
More details to come.
