We load a helper class, which is the sessions factory with the webapp.

>From web.xml:


public class RequestScopeHibernateSession implements ServletRequestListener 
	public static final String PREFIX;
	public final String KEY;
	/** This method will fetch a hibernate session from request scope,
stored under KEY **/
	public static Session getSession(ServletRequest request);
	/** This method will close the session and execute the needed rollback
if there is a dirty transaction **/
	public void requestDestroyed(ServletRequestEvent arg0);
	/** This method will register this object into the request scope, under
KEY. **/
	public void requestInitialized(ServletRequestEvent arg0);

While what you saw may indeed be very bad, DAO is not always an answer either.
