Hi

I have a problem with initializing hibernate (instantiating and configuring caches; ExceptionInInitializerError):

797 [main] DEBUG net.sf.hibernate.connection.DriverManagerConnectionProvider - returning connection to pool, pool size: 1
797 [main] INFO net.sf.hibernate.cfg.SettingsFactory - Use scrollable result sets: true

Exception in thread "main"

It seems that there is a problem with the class-loader
