That didn't help. All the time I'm receiving NoResultException in MDB when trying to retrieve numbers from database. It's like the data I've persisted are not commited. This effect do not happen all the time. It happens from time to time and in all cases for first or second message that is processed. When I was testing today I've noticed that MDB starts to retrieve data in the moment transaction in servlet is commited.
