Problem with JAX-RS services in the last CXF snapshot.
Hi,
I'm trying to integrate the JAX-RS implementation now included in CXF 2.1
(snapshot).
The service is correctly called and the parameters arrive fine but then I
get a page with the message:
No message body writer found for response class : SimpleResponse.
Where SimpleResponse is my custom response bean extending the
javax.ws.rs.core.Response.
Here the code:
@Path("/ButtonService")
public class ButtonWebServiceImpl implements ButtonWebService {
@Path("/addressButton/{action}/{apiKey}/{countryCode}/{state}/{city}/"
+
"{street}/{number}/{postCode}/{attribution}/{logoUrl}/{name}/{description}/{source}/{buttonServer}/{buttonArtUrl}")
@GET
public SimpleResponse createForAddress(@PathParam(value = "action")
String action, @PathParam(value = "apiKey")
String apiKey, @PathParam(value = "countryCode")
String countryCode, @PathParam(value = "state")
String state, @PathParam(value = "city")
String city, @PathParam(value = "street")
String street, @PathParam(value = "number")
String number, @PathParam(value = "postCode")
String postCode, @PathParam(value = "attribution")
String attribution, @PathParam(value = "logoUrl")
String logoUrl, @PathParam(value = "name")
String name, @PathParam(value = "description")
String description, @PathParam(value = "source")
String source, @PathParam(value = "buttonServer")
String buttonServer, @PathParam(value = "buttonArtUrl")
String buttonArtUrl) {
...
}
}
and in Spring:
<jaxrs:server id="buttonWebServiceRest"
address="/rest/">
<jaxrs:serviceBeans>
<ref bean="buttonWebServiceImpl" />
</jaxrs:serviceBeans>
</jaxrs:server>
Have any glue on that?
Further questions:
- My SimpleResponse extend the javax Response as I red in the JAXRS new
documentation that this is a requirement for the HTTPMerthod annotation. Is
this valid also for the @GET annotation? How I have to implement it?
- Before the JAXRS implementation I always used to put the annotations at
the interface level but now in this way it doesn't seem to work anymore. I'm
missing something to make it possible? Maybe is this a JAXRS specification?
Thanks in advance,
Vicio.

It worked! :-)
So now I'm just returning:
return Response.ok(simpleResponse).build();
where the SimpleResponse class has the @XmlRootElement annotation on top.
Thank you very much for your help,
V.

Hi
MessageBodyWriter.isWriteable() checks if a given type can be
serialized, so if say you custom type has no JAXB annotations then no
matching writer will be found. You may want just to add @XmlRootElement
to the root of your class, alternatively you can register your custom
writer. Please check the JAXRS system tests on how this can be
done...(I'm sorry, at the moment that's our documentation :-)).
Typically You don't need to extend a Response, Response is a convenience
holder for a status, the entity and response headers
Cheers, Sergey

Looking at the CXF code it seems the problem is here:
private <T> MessageBodyWriter<T> chooseMessageWriter(
List<MessageBodyWriter> writers, Class<T> type, MediaType
mediaType)

if (!ep.isWriteable(type)) {

Hi
I think you need to return a Response and then in your code do :
return Response.setEntity(yourObject).build()
I think that just by the virtue of extending a Response you can not have it serialized.

I've seen on a Jersey list recently that it's a feature of the 0.7 API (spec), we're at a 0.6 level currently...
and that annotations will only be supported at a method level, don't know more about it at this stage
