(Newbie) tomcat: Error reading resource

brando · **Joined:** Wed Aug 25, 2004 11:53 am **Posts:** 3

I've tried hard to get my proof of concept to work, but am stuck. Tomcat is throwing the exception as noted below. Where am I going wrong? Any help would be appreciated! Cheers - Randy Troppmann

Hibernate ver 2.1
Database: Postgresql 7.4
Container: Tomcat 5.0.16

Servlet code:

Code:

    try {   
       sessionFactory = new Configuration().configure().buildSessionFactory();       
       Session session = sessionFactory.openSession(); 
       Transaction tx;
       tx = session.beginTransaction();
       Athlete athlete = new Athlete();
       athlete.setUserName("SteveTroppmann");
       athlete.setFirstName("Stevie");
       session.save(athlete);
       tx.commit();
       session.close();
    }
    catch (Throwable ex) {
       System.out.println("Randy: Error in servlet");
        throw new ExceptionInInitializerError(ex);
    }

Athlete.hbm.xml

Code:

<?xml version="1.0"?>
 <!DOCTYPE hibernate-mapping PUBLIC

   </class>
</hibernate-mapping>

hibernate.cfg.xml

Code:
