EntityManager.joinTransaction()method. The persistence context remains joined to the transaction until the transaction commits or rolls back. After the transaction commits or rolls back, the persistence context will not be joined to any subsequent transaction unless the joinTransaction method is invoked in the scope of that subsequent transaction. Such a persistence context must not be flushed to the database unless it is joined to a transaction. The application's use of queries with pessimistic locks, bulk update or delete queries, etc. result in the provider throwing
TransactionRequiredException. After the persistence context has been joined to the JTA transaction, these operations are again allowed.
