hibernate configuration file and SessionFactory

Question

I am struggling at the moment to find out why I get this error messages. I'm using hibernate for the first time so that I could have configured something wrong.

IMO it could be one of this 3 problems.

• My hibernate.cfg.xml file is at the wrong "place" but I didn't change the classpath and the hibernet file is inside the src folder.

• I get a warning at the line where I create a new SessionFactory SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); There are 2 types which i can get back from buildSessionFactory()

  1. SessionFactory
  2. Configuration

Of course I took SessionFactory but maybe I overlook something.

package hibernate;
 import java.util.Date;

 import org.hibernate.Session;
 import org.hibernate.SessionFactory;
 import org.hibernate.cfg.Configuration;

 import persistencelayer.*;

 public class HibernateTest {

 public static void main(String[] args) {

    TestUserDetails user2 = new TestUserDetails();
    user2.setUserId(1); 
    user2.setUserName("First User");
    user2.setAddress("First User's address");
    user2.setJoinedDate(new Date());
    user2.setDescription("Description of the user goes here");

    try {
    //SessionFactory wird erzeugt, mit der Konfiguration von Hibernate
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();
    session.beginTransaction();

 //     session.save(user);

    session.save(user2);
    session.getTransaction().commit();
    } catch (Exception e) {
        System.out.println("Fehler beim erstellen der SessionFactory");
    }



}

}
`

• It could also be that i configured my hibernate.cfg.xml file wrong. I am deleting the username, password and host, for safety reasons.

I am trying to find the solution since google but it is simply not working. I am using Oracle as DB btw.

Suggestions would be appreciated. Thank you in advance and sorry for the long post :).

Answer 1

i have found the problem it is inside the hibernate.cfg.xml file.

i copied it from the offical hibernate 4.3.9 files. This section is wrong.

<property name="hibernate.connection.password" />password</property>

there should not be a "/" on the left side where password is meant to be put in.
