List of joinTransaction() Examples

Examples of joinTransaction()

javax.persistence.EntityManager.joinTransaction()
Indicate to the EntityManager that a JTA transaction is active. This method should be called on a JTA application managed EntityManager that was created outside the scope of the active transaction to associate it with the current JTA transaction. @throws IllegalStateException if this EntityManager has been closed @throws TransactionRequiredException if there isno transaction.

Examples of javax.persistence.EntityManager.joinTransaction()

             * Since the Entity Manager (EM) is not managed by the container the developer must explicitly tell the EM
             * to join the transaction. Compare this with ManagedComponent where the container automatically
             * enlists the EM with the transaction. The persistence context managed by the EM will then be scoped
             * to the JTA transaction which means that all entities will be detached when the transaction commits.
