I am building a portlet which uses hibernate. I was orginially using the hibernate.cfg.xml file, however I kept getting a WARN about not being able to get connection metadata and then I would get an exception "Caused by: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory, caus
e: connection broken.

Well n-e-way for the time being I figured I could just go back to using a hibernate.properties file in my classes rt. I had to go into my HibernateUtil file and change
sessionFactory = new Configuration.configure().buildSessionFactory();

to

sessionFactory = new Configuration().buildSessionFactory();

Now without any mapping files this worked fine. However then I went back into my HibernateUtil file and changed it to be this:

Configuration conf = new Configuration();
conf.addClass(Cat.class);
// Create the SessionFactory
sessionFactory = conf.buildSessionFactory();

Now I get this error: Below the error is the hbm and bean for Cat

Anyone have any ideas why I am getting the CGLIB error?

Probably you use two cglib versions in the same application(there are two "KeyFactory" versions in your application). Try to move stuff web-inf/lib and clear all shared "class" and "lib" directories.
