Thread-topic: Eclipselink 2 / JPA 2 integration with Spring on WebLogic 12.1.1

Michael,

Hi, I will look into your spring configuration when I get back into the office later today.

If you switch from EE container managed spec development to VMWare spring development – your configuration could change in several ways depending on whether you are running the spring DI container in your WAR or EJB container.

From a quick look on my IPhone, the CNFE exception is due to the persistence unit and entity classes being in different classloaders. The weaving exception I will need to look at. Normally the EJB container proxy handles this without Spring.

Subject: Eclipselink 2 / JPA 2 integration with Spring on WebLogic 12.1.1

Hi Michael,

Thank you for your help on trying to make JPA 2 / EclipseLink 2 to work on Weblogic 10.3.4. I have been able to persuade my superiors to move to WebLogic 12.1.1.

However, I am having a bit of a problem trying to deploy my persistence.xml. I have changed my design a bit. Now, instead of an EJB I am using a Spring configured DAO class (I am integrating my piece into a larger Spring-configured application). I use the same entities. I believe my problem is due to the Spring configuration.

That’s how my project looks like:

DAO Class

package dti.admin.cp.dao;

import dti.admin.cp.entity.ConfigEventHeader;

import org.springframework.stereotype.Component;

import org.springframework.transaction.annotation.Transactional;

import javax.persistence.EntityManager;

import javax.persistence.PersistenceContext;

import javax.persistence.Query;

import java.util.List;

@Component

public class ConfigEventHeaderDao {

@PersistenceContext(unitName = "ConfigPropsPU")

private EntityManager em;

@Transactional

public void persist(Object object) {

em.persist(object);

}

/**

* Returns a list of ConfigEventHeader objects in the database

* @return List<ConfigEventHeader>

public List<ConfigEventHeader> retrieve() {

Query query = em.createNamedQuery("ConfigEventHeader.findAll");

System.out.println(new java.sql.Timestamp(System.currentTimeMillis()) + " -- "

+this.getClass().getName()+ " -- "+"Retrieving a List ConfigEventHeaders...");

return query.getResultList();

}

/**

* Update the ConfigEventHeader record

* @param configEventHeader object to be updated

* @return Customer

@Transactional

public ConfigEventHeader update(ConfigEventHeader configEventHeader) {

System.out.println(new java.sql.Timestamp(System.currentTimeMillis()) + " -- "

+this.getClass().getName()+ " -- "+"ConfigEventHeader Update: "+configEventHeader.getConfigEventHeaderPk());

return em.merge(configEventHeader);

}

public ConfigEventHeader findByEntityPk(ConfigEventHeader configEventHeader) {

Query query = em.createNamedQuery("ConfigEventHeader.findByConfigEventHeaderPk");

System.out.println(new java.sql.Timestamp(System.currentTimeMillis()) + " -- "

+this.getClass().getName()+ " -- "+"findByEntityPk ConfigEventHeader: "+configEventHeader.getConfigEventHeaderPk());

return (ConfigEventHeader)query.getSingleResult();

}

public ConfigEventHeader loadById(Long id) {

System.out.println(new java.sql.Timestamp(System.currentTimeMillis()) + " -- "

+this.getClass().getName()+ " -- "+"Loading ConfigEventHeader by Id: "+id);

return em.find(ConfigEventHeader.class, id);

}

@Transactional

public void delete(ConfigEventHeader configEventHeader){

System.out.println(new java.sql.Timestamp(System.currentTimeMillis()) + " -- "

+this.getClass().getName()+ " -- "+"Deleting ConfigEventHeader: "+configEventHeader.getConfigEventHeaderPk());

em.remove(em.merge(configEventHeader));

}
