Hello there,
I use glassfish and just wanna do hibernate's criteria search.
But I only get
Code:
final org.eclipse.persistence.sessions.Session session = ((org.eclipse.persistence.internal.jpa.EntityManagerImpl) em.getDelegate()).getSession();
instead of
Code:
org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession();
How can I inject the hibernate implementation?
my Service class
Code:
package de.familienschaetze.dao;
import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import java.util.List;
import java.util.Map;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.criterion.Criterion;
import org.hibernate.criterion.Example;
import org.hibernate.criterion.Projections;
import de.familienschaetze.entities.EntityWithId;
public class GenericDaoImpl<T extends EntityWithId, ID extends Serializable> implements GenericDao<T, ID> {
@PersistenceContext
protected EntityManager em;
protected List<T> findByCriteria(final Criterion... criterion) {
// JBOSS verwendet (Session) em.getDelegate()
// aeltere Glassfish verwendet org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession();
final org.eclipse.persistence.sessions.Session session = ((org.eclipse.persistence.internal.jpa.EntityManagerImpl) em.getDelegate()).getSession();
final Criteria crit = session.createCriteria(getEntityClass());
return result;
}
hibernate versions I use:
Code:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.5.6-Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>3.6.8.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-commons-annotations</artifactId>
<version>3.3.0.ga</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.8.Final</version>
</dependency>
my persistence.xml
Code:
<?xml version="1.0" encoding="UTF-8"?>

thanks alot for help.
Your houk
ps. : The following hint doesnt work for me (but perhaps other guys with same problem):
