In a service factory setting up the request fail handler is optional, and in case we don't specify a fail handler a default one will be used, the default response handler from domino-rest will just log the exception. we can override the default fail handler using DominoRestConfig.
@RequestFactory
public interface MoviesService {
@Path("library/movies/:movieName")
@GET
Movie getMovieByName(@PathParam("movieName") String movieName);
@Path("library/movies")
@GET
List<Movie> listMovies();
@Path("library/movies/:name")
@PUT
@SuccessCodes({200})
void updateMovie(@beanParam @RequestBody Movie movie);
}
