I use Hibernate 5.2.1 V with wildfly 10.0.1

When I call, criteria.getList() I get session/entitymanager closed exception.

Can somebody point me why I get this issue?

My code is like;


Code:
@TransactionAttribute(TransactionAttributeType.REQUIRED)
   public void insertOrUpdate(T entity) {
      
      try {
         List<T> resultList = null;
         if (entity.getCode() != null && entity.getId() ==null) {
            resultList = crud().criteria(crud().eq("code", entity.getCode()).getCriteria()).list(); //---> Gives issue


Code:
List<T> result = getCriteria().list();  //Issue.
   


I create criteria instance as follows;


Code:
criteria = getSession().createCriteria(getEntityClass());



I create session like;

Code:
   public Session getSession() {
      if (session == null || !session.isOpen()) {
         session = getEntityManager().unwrap(Session.class);
      }
      return session;
   }

And do you inject the EntityManager into your EJB?

Yes.
Like;
Code:
@Stateless
public class AddressService extends CrudService<Address> {

@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void insert(Address entity) {
EntityManager em = crud().getEntityManager();
em....

super.insert(entity);
}

}


Code:
@TransactionAttribute(TransactionAttributeType.SUPPORTS)
public class Crud<T extends BaseEntity> implements Serializable {
@PersistenceContext
   protected EntityManager entityManager;

public EntityManager getEntityManager() {
      return entityManager;
   }

}

You have to add a debug breakpoint in the EntityManager#close method because it's not clear why the EntityManager got closed in your use case.

I could not set with break points because,this happens in a loadtest. When i do concurrent level 10 with a load this occurs.

I use Container Managed transaction.

Am I doing anything wrong in my Transaction attribute setting?

Code:
@TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void insertOrUpdate(T entity) throws DBException {

..
    if (entity.getCode() != null && entity.getId() == null) {
                resultList = base().criteria(base().eq("code", entity.getCode()).getCriteria()).list();  //gives issue
            }
..
}



     @TransactionAttribute(TransactionAttributeType.SUPPORTS)
        public class Base {

        ..
            public List<T> list() {
                List<T> result = getCriteria().list();  //gives issue
                resetCriteria();
                return result;
            }
...
}



I get session like;

Code:
@PersistenceContext
    protected EntityManager entityManager;


session = getEntityManager().unwrap(Session.class);
