Kaloyan Kolev closed WINK-218.
------------------------------
Resolution: Invalid
The issue turned out to be a problem with the JAXBXmlProvider so this issue
will be reopened with the proper description.
> GenericEntity's generic type is not used when choosing provider.

> Project: Wink
> Issue Type: Bug
> Components: Common
> Affects Versions: 0.2
> Reporter: Kaloyan Kolev
>
> I have created a subclass of the AtomEntry, let's say XAtomEntry. When I
> return that as an entity resource I get exception that there is no provider
> for that type. The exception is thrown by FlushResultHandler. I tried to wrap
> the new type in a GenericEntity with a generic type set to AtomEntry, but the
> result was the same.
> Here is the check for the GenericEntity:
> {code}
> Class<?> rawType = null;
> if (entity instanceof GenericEntity) {
> GenericEntity<?> genericEntity = (GenericEntity<?>)entity;
> entity = genericEntity.getEntity(); // this is the XAtomEntity
> instance
> rawType = genericEntity.getRawType(); // this is the XAtomEntity
> class
> genericType = genericEntity.getType(); // this is the AtomEntity
> class
> } else {
> rawType = (entity != null ? entity.getClass() : null);
> if (isOriginalEntityResponseObj) {
> genericType = rawType;
> } else {
> genericType = (genericType != null ? genericType : rawType);
> }
> }
> {code}
> This should match the default JAXBXmlProvider, right?
> Later a provider is searched for:
> {code}
> // get the provider to write the entity
> Providers providers = context.getProviders();
> MessageBodyWriter<Object> messageBodyWriter =
> (MessageBodyWriter<Object>)providers.getMessageBodyWriter(rawType,
>
> genericType,
>
> declaredAnnotations,
>
> responseMediaType);
> {code}
> Here the messageBodyWriter is set to null.
