WebLogic Server supports Java Transaction API (JTA), which you can use to implement distributed transactional applications. There are two ways to begin a transaction: explicitly with a user transaction or automatically using the EJB container. To do this you set the isolation level for the transaction. The isolation level defines how concurrent transactions accessing a persistent store are isolated from one another for read purposes.
