6.17. Reviewing Iteration 2

In Iteration 2, we moved all business logic out of the Controller Servlet into the InventoryFacadeBean (which groups our synchronous activities and wraps the DAO). We took the following steps:

• Moved the business logic from the Controller Servlet's actions into the InventoryFacadeBean.

• Modified the Controller Servlet to call the new methods in the InventoryFacadeBean.

• Modified the HibernateCarDAO to work with CMT by removing the transaction setup and tear down code. We also removed the code that closes Hibernate Sessions.

• Changed the ServiceLocator's getHibernateSession( ) method to work with CMT by calling the SessionFactory's getCurrentSession( ) method.
