I am very new to Hibernate. I am trying to follow the first tutorial for 4.1.6 Final. Following is the
http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html_single/#tutorial-firstapp-setup
I setup the project using maven and use the same codes from the tutorial. When I tried to run the EventManager, I got following exceptions.
Code:
Initial SessionFactory creation failed.org.hibernate.InvalidMappingException: Could not parse mapping document from resource org/hibernate/tutorial/domain/Event.hbm.xml

Could anyone help me on this?
The other problem I have is that the way to create a service SessionFactory in tutorial is actually using a deprecated method.
conf.configure().buildSessionFactory()
I wonder if there is better way to create the factory.
