RESTful service returning objects that don't have XmlRootElement

[John Mikhail <jm...@gmail.com>]

Hello,

So for the RESTful service I'm writing, I generated my data model from a
third party xsd.  All the objects created there don't have a @XmlRootElement
annotation, but rather just @XmlType. So when I return these objects from my
RESTful service, I'm now getting:

.No message body writer found for response class : LocationOptionsType.

I dug around online and didn't really find anything helpful.  I did find one
post that said there should be an ObjectFactory that has methods that I can
use to wrap my classes in a JAXBElement.  I tried using that, but everything
I'm doing returns that error.

I tried modifying my method signature to return the object itself, the
JAXBElement wrapped object, and even a Response, but all the same.  Has
anyone run into this issue?

Thanks in advance,

John

Hi

Support for JAXBElement and custom ContextResolvers is coming very shortly. I'm slowly doing some CXF JAX-RS background work around fixing various issues and upgrading it to later api versions. Still, there's a possible workaround : you can simply copy and paste an existing JAXBProvider and in its writeTo() element add a check :

if (JAXBElement.class is assignable to a passed in Class type) then pass in the type/object returned from the JAXBElement to the the JAXB marshaller instead...and then register it from Spring and your provider will be picked up and used...

Cheers, Sergey
