JAXRS - method consumes application/xml + application/json

[J. Fiala]

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
