Every exception that happens within this rest api I have been working on ends up being logged in Jboss as SEVERE.

This seems too harsh for what we need at the moment.

I implemented a WebApplicationExceptionMapper and tried to make the exceptions being logged as ERROR instead and then return a Response object that holds the status and message that came already as a result of the failure.

Something like this:

public class WebApplicationExceptionMapper implements ExceptionMapper<WebApplicationException> {

    private static final Logger logger = LoggerFactory.getLogger(WebApplicationExceptionMapper.class);

    @Override
    public Response toResponse(WebApplicationException exception) {
        logger.error("WebApplicationException thrown [statusCode: {}]", exception.getResponse().getStatus());
        return Response.status(exception.getResponse().getStatus())
                       .entity(exception.getMessage())
                       .build();
    }

}

It seems to me like this is not really working, can anyone help?

Thank you very much!
