Transaction management in Hibernate

A transaction is an atomic unit of work. There are only two outcomes, either success or failure. In hibernate one way to manage transactions is as given below.

Session session = null;
Transaction tx = null;
try {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    //perform the transactions here
    // some more transactions
    tx.commit();
} catch (RuntimeException ex) {
    tx.rollback();

} finally {
    session.close();
}
