the exception is in this lines of code

public Aucas() {
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();
    LoginDialog d = new LoginDialog(null,false,this);
}

You need to check for conflicting version of class org.apache.log4j.Level in your classpath and resolve it. The TRACE level is available in the log4j jar of version 1.2.12 or higher.
