I know it is a very easy question but I don't know what to do and I don't find a answer outside in the net.

I use HibernateTools 3.2 beta8 and eclipse 3.2.

I used the reverse engineering function from hibernate and generated me fhe DAO, Domain Code and Mapping files.

Now I wanted to get some data out of the Table or insert some but everything I try fail.

I won't paste the files generated from Hibernate, because I think you know how they look like.
I also generated a HibernateUtil file, because I read about this but I also get an error. So if you can help me or know a good tutorial, I would be happy.

HibernateUtil
Code:
package de.fhg.scai.bio.csr.io.database.communication;

import org.hibernate.*;
import org.hibernate.cfg.*;

public class HibernateUtil {

    private static final SessionFactory sessionFactory;

    static {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            sessionFactory = new Configuration().configure().buildSessionFactory();
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}


Error

your stacktrace doesn't show any hibernate - just your code looking up in jndi.

this is nothing specific to the tools - better to ask in the user forum.
