Persist problem

[Mamadou Touré]

Hi,

I wrote en EJB that is called by a servlet, but when it comes to persiting the data, the operation is executed without error, but table is still empty (I don't see the record that has been persisted). I use TopLink as persistence tool. So could someone tell me what's wrong


here is my code

 /*

 * and open the template in the editor.
 */

package com.flight.ejb;

import com.flight.transferObject.PassengerTO;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

/**
 *
 * @author mtoure
 */
@Stateless
public class SessionPassengerBean implements SessionPassengerLocal {
    @PersistenceContext(unitName="flight" )
    private EntityManager em;


    public void addPassenger(PassengerTO pTO)
    {
        Passenger pass = new Passenger();
        pass.setPaddress(pTO.getPAddress());
        pass.setPcode(pTO.getPCode());
        pass.setPemail(pTO.getPEmail());
        pass.setPfname(pTO.getPFname());
        pass.setPfreqfly(pTO.getPFreqFly());
        pass.setPlname(pTO.getPLname());

         em.persist(pass);
         em.flush();
      
        

    }
    
    // Add business logic below. (Right-click in editor and choose
    // "Insert Code > Add Business Method" or "Web Service > Add Operation")
 
}

What persistence framework you user behind the jpa? If you use Hibernate, change the show_sql to true for show the SQL and look if the Insert is be generated. Check the transaction too, because if not persists data in database then a container isn't create a transaction for operation.

I use TopLink. Now I don't even see the records that I have in others tables. It seems that my SELECT * FROM ..... doesn't work anymore, it returns nothing.
