Example 1 with EntityInputStream

use of org.glassfish.jersey.message.internal.EntityInputStream in project jersey by jersey.

the class AbstractJaxbElementProvider method readFrom.

@Override
public final JAXBElement<?> readFrom(Class<JAXBElement<?>> type, Type genericType, Annotation[] annotations, MediaType mediaType, MultivaluedMap<String, String> httpHeaders, InputStream inputStream) throws IOException {
    final EntityInputStream entityStream = EntityInputStream.create(inputStream);

        throw new NoContentException(LocalizationMessages.ERROR_READING_ENTITY_MISSING());
    }
    final ParameterizedType pt = (ParameterizedType) genericType;
