If you don't want to use cache:



Else change it to some other cache provider impl.

There is no class org.hibernate.cache.NoCacheProvider

The Error is
org.hibernate.HibernateException: could not instantiate CacheProvider: org.hibernate.cache.NoCacheProvider

Which version of Hibernate do you use?

In 3.1 NoCacheProvider exists.
Otherwise write one yourself - simple noimpl class.
