>             Project: Application Server 7
>          Issue Type: Bug
>          Components: REST
>    Affects Versions: 7.1.1.Final
>         Environment: JBoss AS 7.1.1

> This doesn't work:
> {code}
> @Provider @Produces(MediaType.APPLICATION_JSON)
> public class JacksonContextResolver implements ContextResolver<ObjectMapper> {
> 	private transient Logger log = LoggerFactory.getLogger(JacksonContextResolver.class);
> 	private ObjectMapper objectMapper;
> 	public JacksonContextResolver() throws JsonGenerationException, JsonMappingException, IOException {
> 		log.info("Using my own Jackson ObjectMapper");
> 		objectMapper = new ObjectMapper();
> 		objectMapper.configure(Feature.INDENT_OUTPUT, true);
> 		objectMapper.configure(Feature.WRITE_DATES_AS_TIMESTAMPS, false);
> 		objectMapper.configure(Feature.WRITE_DATE_KEYS_AS_TIMESTAMPS, false);
> 		
> 		log.info("Test date: {}", objectMapper.writeValueAsString(new DateTime()));
> 		log.info("Test pretty output: {}", objectMapper
> 				.writeValueAsString(new Article("Launching AksiMata",
> 						"AksiMata : Ada apa di sana?",
> 						"Webapp yang keren dan oke punya.", "Hendy Irawan")));
> 	}
> 	
> 	@Override
> 	public ObjectMapper getContext(Class<?> type) {
> 		return objectMapper;
> 	}
> }
> {code}
> The log correctly tests the custom ObjectMapper works fine, however when returning the output, seems like it's still using the "default" ObjectMapper.
> This also doesn't work:
> {code}
> @Override
> public Set<Object> getSingletons() {
> 	Set<Object> singletons = new HashSet<Object>(super.getSingletons());
> 	ObjectMapper objectMapper = new ObjectMapper();
> 	objectMapper.configure(Feature.INDENT_OUTPUT, true);
> 	objectMapper.configure(Feature.WRITE_DATES_AS_TIMESTAMPS, false);
> 	objectMapper.configure(Feature.WRITE_DATE_KEYS_AS_TIMESTAMPS, false);
> 	singletons.add(objectMapper);
> 	return singletons;
> }
> {code}
> Sample project to reproduce the issue is at:
> https://github.com/soluvas/ear-sample/tarball/resteasy-jackson-bug
> After deploy, check the output via:
> http://localhost:8080/api/article/
> Bug is almost similar to #AS7-1408.
