You may use the org.eclipse.persistence.jpa.JpaHelper class to obtain an EntityManager.
Using a server session
EntityManagerFactory emf = org.eclipse.persistence.jpa.JpaHelper.createEntityManagerFactory(serverSession); EntityManager em = emf.createEntityManager();
Using a sessions.xml file
If you want to use EclipseLink or Oracle TopLink's native XML metadata within EclipseLink JPA this can be accomplished using API:
EntityManagerFactory emf = org.eclipse.persistence.jpa.JpaHelper.createEntityManagerFactory(sessionName); EntityManager em = emf.createEntityManager();
or through the use of persistence unit properties:
TODO: Example of XML property config
TODO: Example of property config using properties map passed to Persistence.createEntityManagerFactory("pu-name", properties)
