Thanks Sergey
I tried 2.7.6-SNAPSHOT with no luck, same error.
So I then tried to fix this by wrapping the provider, but still get the
same problem. I'm not 100% sure on the implementation, would you mind
taking a look at it below and let me know if i'm missing anything?
Cheers, Nic
class JacksonJsonProviderWrapper implements MessageBodyReader<Object>,
MessageBodyWriter<Object>, Versioned {
private JacksonJsonProvider jjp = new JacksonJsonProvider();
@Override

return jjp.version();

public void setMapper(ObjectMapper m) {
jjp.setMapper(m);
}
@Override
public boolean isWriteable(Class<?> type, Type genericType, Annotation[]
annotations, MediaType mediaType) {
return jjp.isWriteable(type, genericType, annotations, mediaType);

I have just upgraded from Jackson 2.1.1 to 2.2.2 and it has caused the
following exception:
javax.ws.rs.client.ClientException: .No message body writer has been

Has something changed in the way I need to configure the provider?
Known issue, has been fixed for CXF 2.7.6-SNAPSHOT, Jackson 2.2 class
hierarchy has become more complex and that confused the runtime.
Very easy workaround is to wrap Jackson 2.2.x provider in a custom
provider which only delegates to Jackson all of its calls
