I am try to write sample using Hibernate with Axis2. But I have the following errors:
Caused by: java.lang.ExceptionInInitializerError
at org.test.persistence.HibernateUtil.createSessionFactory(HibernateUtil
.java:15)

this is services.xml

HibernateUtil.java
package org.test.persistence;

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

public class HibernateUtil {

private static SessionFactory sessionFactory;

public static void createSessionFactory() {
try {
sessionFactory = new Configuration().configure()
.buildSessionFactory();
} catch (Exception e) {
}

}

public static Session getSession() {
return sessionFactory.openSession();
}
}

I don't know how to load xml configuration, if you have sample and link, please send it to me: trinhnt@gmail.com Thanks so much!!!
