Andrei Ivanov commented on CXF-7825:
------------------------------------
Hmm, my problem is with the request, not with the response, as those
definitions are accepted fine by the generator.
> wadl2java: support multiple representations of the same element

> Key: CXF-7825
> URL: https://issues.apache.org/jira/browse/CXF-7825
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS, Tooling
> Affects Versions: 3.2.6
> Reporter: Andrei Ivanov
> Priority: Major
>
> Hi,
> I have little experience using WADL and I'm trying to define a resource
> which accepts a request parameter with multiple representations (JSON and
> XML):
> {code:xml}
> <resource id="PaymentManagementService" path="/paymentmanagement">
> <resource path="/transaction/{uuid}">
> <doc>Store a Payment corresponding to the specified transaction</doc>
> <param name="uuid" style="template" type="ns:uuid" />
> <method id="storePayment" name="PUT">
> <request>
> <representation mediaType="application/json"
> element="ns:Payment" />
> <representation mediaType="application/xml"
> element="ns:Payment" />
> </request>
> <response status="200" >
> <doc>Returns the newly stored payment</doc>
> <representation mediaType="application/json"
> element="ns:Payment" />
> <representation mediaType="application/xml"
> element="ns:Payment" />
> </response>
> <response status="500" >
> <doc>Storing of the payment failed</doc>
> <representation mediaType="application/json"
> element="ns:ExceptionDetails" />
> <representation mediaType="application/xml"
> element="ns:ExceptionDetails" />
> </response>
> </method>
> </resource>
> </resource>
> {code}
> As far as I see, after CXF-3797, the generator doesn't handle this scenario,
> considering them as different types.
> I've also tried this way, which I'm not even sure is correct, but the
> generator seems to generate correct code, which is a single method which
> consumes the 2 media types:
> {code:xml}
> <representation mediaType="application/json">
> <param name="payment" style="query" type="ns:Payment" />
> </representation>
> <representation mediaType="application/xml">
> <param name="payment" style="query" type="ns:Payment" />
> </representation>
> {code}
> {code:java}
> @Path("/paymentmanagement")
> public interface PaymentManagementService {
> /**
> * @return Returns the newly stored payment
> */
> @PUT
> @Consumes({"application/json", "application/xml" })
> @Produces({"application/json", "application/xml" })
> @Path("/transaction/{uuid}")
> Payment storePayment(@PathParam("uuid") String uuid, Payment payment);
> }
> {code}
> The problem with this approach is that now I'm trying to enable _bean
> validation_, but the generator ignores this 2nd approach representations
> because it doesn't find an {{element}} attribute on the representations.
> Not sure what the solution is, maybe just update the generator to handle the
> 1st approach properly.
