OK, I've hooked up a real simple project with a Customer bean having
@XmlRootElement. It works out the of box with an Application activator
returning a JacksonJaxbJsonProvider.
I've switched on SerializationFeature.WRAP_ROOT_VALUE to mirror our XML api
documentation a little closer. Two things are otherwise immediately
apparent:
1. The JSON has an empty root name:
{
"": {
"id": 2
}
}
Unless I expressly set the name of the @XmlRootElement. Can't find
reference to this on Google though. Any ideas?
2. I have switched off SerializationFeature.WRITE_DATES_AS_TIMESTAMPS again
to mirror our XML API docs closer. My reading of the JavaDocs suggests that
although not thread-safe by itself, the formatter is here only used by
thread-safe framework methods. Is this correct?
I've run out of time to investigate tonight. I'll continue with my tiny app
to try and get a representation does not differ from XML unnecessarily and
post an update.
Thank you once more for your time.
James
