Major Description
My service returns SortedSet<Movie>, where Movie is a JAXB annotated class. The resulting XML is given below.
On the client side, I have a custom MessageBodyReader as given below. The issue is that the Unmarshaller always returns an empty TreeSet.
MovieSetMessageBodyReader.java
@SuppressWarnings("unchecked") @Override public TreeSet<Movie> readFrom(Class<TreeSet<Movie>> type, Type genericType, Annotation[] annotations, MediaType mediaType, MultivaluedMap<String, String> httpHeaders, InputStream entityStream) throws IOException, WebApplicationException { Class<Movie> baseType = Types.getCollectionBaseType(type, genericType); try { JAXBContext ctx = JAXBContext.newInstance(type, baseType); JAXBElement<?> element = ctx.createUnmarshaller().unmarshal( new StreamSource(entityStream), type); return (TreeSet<Movie>) element.getValue(); } catch (JAXBException e) { e.printStackTrace(); } return null; }
MovieServiceRestEasyClient.java
@GET
@Consumes("text/xml")
public SortedSet<Movie> sendRequestByProxy() {
Map<String, Object> requestAttributes = new HashMap<String, Object>();
requestAttributes.put("path", path);
MovieServiceRestEasy proxy = ProxyFactory.create(
MovieServiceRestEasy.class, ENDPOINT, requestAttributes);
ClientResponse<TreeSet<Movie>> response = (ClientResponse<TreeSet<Movie>>) proxy
.getMovieSet(path);
return response.getEntity(TreeSet.class, (new GenericType<TreeSet<Movie>>() {}).getGenericType());
}
