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...
