That said, I looked at the exception below, and I know how to fix it.
So yes, Jackson is obviously not used and what happens now is that a
default JAXB provider is asked to handle it - but it does not know what
the root element of XmlType-only annotated bean is - it does not wrap
automatically (compared to SOAP where the rules are specified).
Two ways to fix it:
- create an instance of CXF JAXBElementProvider, set
'marshallAsJaxbElement' property and register it
- have anonymous complex types -> wadl-to-java will create
XmlRootElement annotated beans in such cases; not sure though how easy
it is to get such types auto-generated with the WADL generator - may be
some extra JAXB properties/annotations can be set or have a prepared
schema linked with WADL generator.

Hey, I'm happy trying to help but let me ask you in return,
do you think 'JacksonJsonProvider' can handle XML ?

Hi,
I have a WADL resource which should accept both xml + json:
<resource path="/hello" id="at.hello.HelloWorldResource">
<method name="POST">
<request>
<param name="name" style="query" type="xs:string"
required="true"/>
<representation mediaType="application/xml"
element="mytypes:MyRequest"/>
<representation mediaType="application/json"
element="mytypes:MyRequest"/>
</request>
<response status="200">
<representation mediaType="application/xml"
element="mytypes:MyResponse"/>
<representation mediaType="application/json"
element="mytypes:MyResponse"/>
</response>
</method>
</resource>
The generated Java source looks like (methods are suffixed with
Xml/Json):
@Path("/hello")
public interface HelloWorldResource{
@POST
@Consumes("application/xml")
@Produces({"application/xml" })
MyResponse postMyRequestXml(@QueryParam("name") String name,
MyRequestType myRequest);
@POST
@Consumes("application/json")
@Produces({"application/json" })
MyResponse postMyRequestJson(@QueryParam("name") String name,
MyRequestType myRequest);
}
If I call the Json method (postMyRequestJson) using JacksonProvider,
everything works.
If I call the Xml method (postMyRequestXml) using JacksonProvider, then
I get an exception:
WARNING: javax.xml.bind.MarshalException
- with linked exception:
[com.sun.istack.internal.SAXException2: unable to marshal type
"at.hello.MyRequest" as an element because it is missing an
@XmlRootElement annotation]
The test is using the JacksonJsonProvider:
JacksonJsonProvider provider = new JacksonJsonProvider();
provider.addUntouchable(Response.class);
List<Object> providers = new ArrayList<Object>();
providers.add(provider);
api = JAXRSClientFactory.create(serverApp,
HelloWorldResource.class, providers);
Any ideas? Or do I have to use another provider for XML?
Best regards,
Johannes
