hibernate 3.2.6 or 3.3.2 and jboss 4.2.3.GA deployed app run fails with c3p0 error

Question

I deploy app having hibernate dependency.

Jboss AS 4.2.3.GA contains hibernate3.jar in server/default/lib.

Tried to load SessionFactory and and get.

With

Googled it with no result.

Substitute hibernate3.jar with hibernate-3.2.6.ga.

and SessionFactory loading hangs somewhere at

    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1339)

at loading of mapping.

Answer 1

Data model class file depended on class which during build was copied to WEB-INF/classes instead of jar.
