I am using Eclipse, and have the following directory structure:

HSLDBsample
+src
++mike.dean
+++CreateTest.java
+++Track.java
+++Track.hbm.xml
++hibernate.cfg.xml

When I run the folllowing test routine, I get to the session.save(track) line but no further:

public static void main(String[] args) throws HibernateException {
SessionFactory sessions = new Configuration()
.configure()
.buildSessionFactory();
// Configuration config = new Configuration();
// config.addClass(Track.class);
// SessionFactory sessionFactory = config.buildSessionFactory();
// Session session = sessionFactory.openSession();
Session session = sessions.openSession();
Track track = new Track();
track.setTitle("Name of the track");
track.setFilePath("The filepath");
track.setPlayTime(new Date());
System.out.println("I get to here");
session.save(track);
session.close();
System.out.println("BUT NOT to here");

}

and the crash indicates:

19:15:53,705 INFO SessionFactoryImpl:366 - Checking 0 named queries
I get to here
Exception in thread "main" org.hibernate.MappingException: Unknown entity: mike.dean.Track

I have tried moving the Track.hbm.xml file all over the place, but at this point I am clearly lost. Any assistance will be appreciated.

Needed to add the Track.hbm.xml to the hibernate.cfg.xml file as is indicated in the documentaiton. Sorry.
