I am using Tapestry 4.0.2 and Honeycomb 0.3.3. For testing purpose, I have changed the configuration file as follows. 1. Create another Hibernate Eager Load Session

2. Create Dao Service (which extends AbstractPersistenceService) that use Hibernate EagerLoad Session

HibernateEagerLoadSession

3. The web project use default honeycomb hibernate session and default honeycomb hibernate session factory. The same errors prompt. Any suggestions? ERROR!
