25 * A KRAD-managed {@link javax.persistence.EntityManagerFactory} factory bean which can be used to configure an
26 * EclipseLink persistence unit using JPA.
27 *
28 * <p>This class inherits the behavior from {@link KradEntityManagerFactoryBean} but adds the following:</p>
29 *
30 * <ul>
31 * <li>Sets the {@link org.springframework.orm.jpa.JpaVendorAdapter} to {@link EclipseLinkJpaVendorAdapter}</li>
32 * <li>Detects if JTA is being used and, if so sets a JPA property value for
33 * {@link PersistenceUnitProperties#TARGET_SERVER} to {@link JtaTransactionController} which allows for
34 * EclipseLink integration with JTA.</li>
35 * <li>Configures an EclipseLink "customizer" which allows for a configurable sequence management strategy</li>
36 * </ul>
