Hi Tristan,
following is a very stupid implementation of such a provider,
you can just try to add com.fasterxml:jackson-xml-databind:0.5.3
dependency to your pom.xml (given that com.sun.jersey:jersey-json:1.7
is already there) and play with that.
The biggest advantage of using this feature is probably the possibility
to get XML out of raw unannotated POJOs, whereas with JAXB you would need
to wrap it using JAXBElement. If you get something useful out of your
experiment,
and you would be willing to contribute that, we could end up adding such
a support
directly to Jersey.

@Provider
@Produces(MediaType.APPLICATION_XML)
public class JacksonXMLMsgBodyWriter implements MessageBodyWriter{
@Override
public boolean isWriteable(Class type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return true;
}
@Override
public long getSize(Object t, Class type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return -1;
}
@Override
public void writeTo(Object t, Class type, Type genericType,
Annotation[] annotations, MediaType mediaType, MultivaluedMap
httpHeaders, OutputStream entityStream) throws IOException,
WebApplicationException {
XmlMapper xmlMapper = new XmlMapper();
xmlMapper.writeValue(entityStream, t);
}
}
