For container-managed transactions, you can use the Admin Console to configure the transaction timeout interval. SeeStarting the Administration Console.
In the Admin Console, expand the Configuration node and select Transaction Service.
On the Transaction Service page, set the value of the Transaction Timeout field to the value of your choice (for example, 5).
With this setting, if the transaction has not completed within 5 seconds, the EJB container rolls it back.
The default value is 0, meaning that the transaction will not time out.
For enterprise beans with bean-managed JTA transactions, you invoke the setTransactionTimeout method of the UserTransaction interface.
