I am using Jersey + Jackson to provide REST JSON services layer for my application. The problem I have is that the default Date serialization format looks like that:

If you choose to work with Joda DateTime objects on your server and want to serialize to ISO8601 you could use Jackson's JodaModule. You can register a Jersey Provider as follows:

import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.joda.JodaModule;

@Provider
public class MyObjectMapperProvider implements ContextResolver {

  final ObjectMapper objectMapper;

  public MyObjectMapperProvider() {
    objectMapper = new ObjectMapper();
    /* Register JodaModule to handle Joda DateTime Objects. */
    objectMapper.registerModule(new JodaModule());
    /* We want dates to be treated as ISO8601 not timestamps. */
    objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
  }

  @Override
  public ObjectMapper getContext(Class arg0) {
    return objectMapper;
  }
}
