I was able to workaround the issue by specifying a String param in my
resource method for receiving the request entity. I then used my JAXB
unmarshaller to unmarshall from a StringReader created with that String.
@PUT
@Consumes({"application/xml"})
@Produces({"application/xml"})
@Path("/requests")
public Response putRequest(String entityStr) {
try {
StringReader reader = new StringReader(entityStr);
Unmarshaller u = ...;
RegistryRequestType req = (RegistryRequestType)
u.unmarshal(reader);
//The req object is now correctly an instance of
RemoveObjectsRequest
...
return response;
} catch (JAXBException ex) {
...
}
}
I am still curious why the behavior I expected is not what jersey server
does.
