Hi
The default Jettison provider expects a namespace-to-prefix map set up.
If you don't realy need the prefixes on the receiving end then the
simplest option is to configure JSONProvider with an "ignoreNamespaces"
property, otherwise you'd need to provide a map, here is more info:
http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-ConfiguringJSONprovider
The thing is how to configure it given that you are using
CXFNonSpringJAXRSServlet.
One option is to extend JSONProvider and only set "ignoreNamespace" or
"namespaceMap" property as needed on the superclass. And register it
with the servlet using a jaxrs.providers parameter.
Another option is try registering Jackson.
I should probably do some enhancement for users be able to set simple
properties on providers registered from web.xml...
Cheers, Sergey

Hello,
I have an issue when I try to get a JSON output, using a JAXB object, of my
REST webservice. (XML output is ok.)
My webservice is running without using Spring.
Can you help me? I don't know how to fix it despite browsing many websites from
Google.
Cheers,
Anthony
