[eclipselink-users] JEE Application Managed EntityManager Error

[jz <jehanzeb.qayyum@xxxxxxxxx>]

Hi All,

I am trying to get application managed entity manager along with container managed. But getting below error:

        @PersistenceContext(unitName = Constants.PERSISTENCE_UNIT)

private EntityManager containerManagedEm;

private EntityManager applicationManagedEm;

@PersistenceUnit(unitName = Constants.PERSISTENCE_UNIT)

private EntityManagerFactory emf;

        @TransactionAttribute(TransactionAttributeType.NEVER)

@PostConstruct

public void init() throws Exception {

applicationManagedEm = emf.createEntityManager();

System.out.println("Active Transaction: "

+ applicationManagedEm.getTransaction().isActive());  //ERROR SEE BELOW

}

Getting error:

Caused by: java.lang.IllegalStateException:

Exception Description: Cannot use an EntityTransaction while using JTA.

        at org.eclipse.persistence.internal.jpa.transaction.JTATransactionWrapper.getTransaction(JTATransactionWrapper.java:65)

        at org.eclipse.persistence.internal.jpa.EntityManagerImpl.getTransaction(EntityManagerImpl.java:1103)

        at com.warid.campaign.service.CampaignCrudBean.init(CampaignCrudBean.java:68)

        ... 87 more

Where:

Environment: Weblogic 10.3.0, Eclipselink 2, JPA 2, Container Managed Transactions
