Failed to set value TransactionScopedEntityManager:EntityManager

[ebross]

Hello JBoss World,

JBossAS [6.1.0.SNAPSHOT "Neo"]

I am consistently having the following error:

Due to unresoved issue [https://issues.jboss.org/browse/JBAS-8803], I have had to place my persistence.xml in an ejb project [myPersistence.jar] created just for the peristence.xml only. myPersistence.jar is packaged in my myEAR.ear; and entities are in a jpa jar and under myEAR.ear/lib.

Here is the rest:

@javax.ejb.Stateless

public class XManagerImpl implements  IXManagerLocal, IXManagerRemote, java.io.Serializable{

@javax.ejb.EJB

private IXDAOLocal dataConstraintDaoReference;

public Future<XEntity[]> queryByExample(final XEntity entity) throws IEJBBaseInterface.ApplicationException{

XEntity[] retList = null;

try{

java.util.Collection<XEntity> results = dataConstraintDaoReference.queryByExample(entity);<----------##ERROR THROWN HERE##

if(results.isEmpty()){

throw new IEJBBaseInterface.EmptyValueException("X results");

}

retList = toArray(results);

  } catch (Exception ex) {

//throw new IEJBBaseInterface.FindObjectException(ex);

ex.printStackTrace();

  }

   return new AsynResult<XEntity[]>(retList);

   }

}

//--------------------------------------------------------------------------------

@javax.ejb.Stateless

public class XDAOImpl extends EclipselinkDAOImpl<XEntity,Long> implements  IXDAOLocal, IXDAORemote, java.io.Serializable{

}

//--------------------------------------------------------------------------------

public abstract class EclipselinkDAOImpl<T extends Persistable<PK>, PK extends Serializable> extends AbstractIGenericDAO<T, PK> implements IEclipselinkDAO<T, PK>, Serializable{

@javax.persistence.PersistenceContext

private JpaEntityManager entityManager;<-------------------------- ##PROBLEM POINT##

}

Injection of the EclipseLink org.eclipse.persistence.jpa.JpaEntityManager is not supported. You can only inject a JPA javax.persistence.EntityManager. This is because a container managed transaction scoped entity manager is an indirection to the underlying entity manager.

Thanks Carlo de Wolf,

The code is almost two years old and running on Jboss 5.1 in production mode; and I have been wondering why I am having all these problems on JBoss6 . Following your response, I did a compare and found that indeed the code in production is:

@javax.persistence.PersistenceContext

private EntityManager entityManager;

public JpaEntityManager getEntityManager() {

if(entityManager == null){

throw new IllegalStateException("EntityManager has not been set before usage");

}

return JpaHelper.getEntityManager(entityManager);

}

How this became JpaEntityManager entityManager in the version I am currently working on, I don't know. Anyway thanks so much!
