500 - Response and Error unless restricting accept header
Hello
When the accept header is set to
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
I get a 500 reponse and the following errr is logged.
2013-01-13 19:27:25,639 [931211918@qtp-341460182-40] ERROR
931211918@qtp-341460182-40org.apache.wink.server.internal.handlers.FlushResultHandler
- The system
could not find a javax.ws.rs.ext.MessageBodyWriter or a DataSourceProvider
class for the org.apache.clerezza.rdf.core.impl.util.PrivilegedGraphWrapper
type and text/html mediaType. Ensure that a
javax.ws.rs.ext.MessageBodyWriter exists in the JAX-RS application for the
type and media type specified.
When I restrict the accept header to a format for which there is a
MessageBodyWriter things works correctly.
Is this a known problem or should I investigate further and create an issue?
Cheers,
Reto

I have created a simple sample application to try to reproduce your
problem, see [1]. In this application, I defined a simple resource :
@Path("/wink379")
public class Resource {
@GET
@Produces(MediaType.MEDIA_TYPE_WILDCARD)
public Response getAll() { ... }
}
And then created a simple message body writer that just output some value back.
public void writeTo( ... ) throws IOException, WebApplicationException {
entityStream.write("Response generated by
ResourceMessageBodyWritter".getBytes());
}
Then used a chrome rest client extension to submit a request like :
GET http://localhost:8080/sample-jaxrs-webapp/services/wink379
Content-Type application/json
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Authorization xxxxx
And I get back the result from the writer :
Response generated by ResourceMessageBodyWritter
Could you please check my sandbox project and see what's different
from your scenario, and help me reproduce your issue.

Hi Luciano
The error occurs when the resource method has no @Produces (or
@Produces(*/*) ) and there is no MessageBodyWriter for the first preference
in the Accept header.

I was trying to reproduce the error with the trunk code, I created a
simple resource that @produces application/xml and then used a browser
rest client to submit a request passing the accept header you
mentioned and it worked ok. Could you double check with trunk code and
maybe provide more details on how I could reproduce the issue.
