In EJB transaction management, only bean-managed transactions (BMT) allow beans to obtain the UserTransaction object via the EJBContext using the getUserTransaction() method. This enables the bean to programmatically control transaction boundaries. In container-managed transactions (CMT), the container controls the transaction boundaries automatically, and beans are not allowed to manually manage transactions using the UserTransaction object.
