JPA Interface EntityTransaction Interface used to control transactions on resource-local entity managers. The EntityManager.getTransaction method returns the EntityTransaction interface. Since: JPA 1.0 The Database Connection using JPA article explains how to use EntityTransaction . Public Methods

It appears that EntityTransaction .commit() does not release a pessimistic lock - test code below. I tried it in with the current (2.7.6_01) and older versions (2.6.9, 2.5.7, 2.4.7) with the same result. (side note: EntityTransaction .rollback() releases it correctly) // Account.java package icke

JPA Method in jakarta.persistence. EntityTransaction void rollback () Roll back the current resource transaction. Throws: IllegalStateException - if {@link #isActive()} is false PersistenceException - if an unexpected error condition is encountered Since: JPA 1.0

JPA Method in jakarta.persistence. EntityTransaction void commit () Commit the current resource transaction, writing any unflushed changes to the database. Throws: IllegalStateException - if {@link #isActive()} is false RollbackException - if the commit fails Since: JPA 1.0
