ejava.examples.ejbsessionbank.blimpl.TellerImpl

All Implemented Interfaces:

Teller

public class TellerImpl
extends Object
implements Teller

This class implements the business logic of the Teller. Its logically implemented in 2 halves; Account and Owner + Account. The Account-only half is used to demonstrate some of the basics. The Owner+Account half is used to add a small amount of complexity to the data model to demo some lazy load issues within the remote facade/EJB layer.
