try catch block does not catch an exception

A try catch block does not catch an exception in a bean. An exception is thrown in method deleteMetaRoute but its try catch block does not catch it.

	@DELETE
	@Path("/{metaRouteId}")
	public StatusElement deleteMetaRoute(
	@PathParam("metaRouteId") int metaRouteId,
	@Context HttpServletRequest req) throws Exception;

	@Override
	public StatusElement deleteMetaRoute(final int metaRouteId,
	final HttpServletRequest req) {
	final String METHOD = "deleteMetaRoute: ";

final StatusElement status = new StatusElement();

	try {
	backend.deleteMetaRoute(metaRouteId);
	status.addSuccess(formSuccess(req, Integer.toString(metaRouteId)));
	} catch (final Exception e) {
	log.debug(METHOD + "error deleting a MetaRoute", e);
	status.addError(formErrorElement(Integer.toString(metaRouteId), e));
	}

	return status;
	}
