> getNotificationEventsCount(NotificationEventsCountRequest rqst) {
> Long result = 0L;
> try {
> openTransaction();
> long fromEventId = rqst.getFromEventId();
> String inputDbName = rqst.getDbName();
> String queryStr = "select count(eventId) from " +
> MNotificationLog.class.getName()
> + " where eventId > fromEventId && dbName == inputDbName";
> query = pm.newQuery(queryStr);
> query.declareParameters("java.lang.Long fromEventId, java.lang.String
> inputDbName");
> result = (Long) query.execute(fromEventId, inputDbName); // <- Here
> commited = commitTransaction();
> return new NotificationEventsCountResponse(result.longValue());
> }
> }
> {code}
> It is possible that query.execute will return null in which case
> rsult.longValue() may throw NPE.
