Hi Francisco,
You should be able to do the following:
bind(JAXBContextResolver.class);
i.e. register it the same way you register a root resource class.
then in the logs you should see something like:
Registering " JAXBContextResolver" as a provider class
If that does not work you might want to check if there are any errors
when constructing JAXBContextResolver.
Paul.
