When I do this:
@GET
@Path("/jobs.xml")
@Produces(MediaType.APPLICATION_XML)
public Response getJobs() {
return Response.ok(getJobsImpls()).build();
}
@XmlType(name = "job", namespace = "http://remote.opencastproject.org/";)
@XmlRootElement(name = "job", namespace = "
http://remote.opencastproject.org/";)
public class JobImpl implements Job {
...
}
I get a 500 response with this in the body "No message body writer has been
found for response class Vector." I thought maybe the problem was that this
Vector is the one being returned by eclipselink, and there was some kind of
proxy voodoo interfering. If I copy all of the JobImpls into a new
ArrayList, I get the same kind of message, "No message body writer has been
found for response class ArrayList."
I'm building the JAX-RS endpoint manually using cxf-bundle-jaxrs-2.2.9.jar
and a CXFNonSpringServlet with some custom providers. Perhaps I'm missing
one of the providers needed to handle Collections?
And I'm curious, what would the xml look like for this collection? Where
does the root element name come from? And the namespace... is it copied
from the objects in the collection?
Thanks,
Josh
