>From the EJB3 Persistence spec (section 5.3, page 116) it says to use:
EntityManagerFactory emf =
| javax.persistence.Persistence.createEntityManagerFactory("Order");
| EntityManager em = emf.createEntityManager();
when working in a Java SE environment.
When working in an EE container use injection/JNDI lookup. For example:
@Stateless
| @TransactionManagement(TransactionManagementType.BEAN)
| public class TravelAgentBean {
|
| @PersistenceUnit(unitName="titan")
| private static EntityManagerFactory factory;
| ...}
|
ps. you can get a UserTransaction with: @Resource UserTransaction tx; if you want to avoid the jndi lookup.
