Implementing the Session Facade Pattern

The session facade pattern contains and centralizes complex interactions between lower-level EJBs (often entity beans). It provides a single interface for the business services of your application.

To implement the session facade pattern using the modeling tools:

Create a session bean, if you have not already done so.
Create a local reference between the beans:
- If you are using the modeling tools, select EJB Local Reference in the Component Palette and click and drag from one bean to another (often from the session bean to the entity bean). For more information, see Modeling a Reference Between Beans.
- If you are using the EJB Module editor, double click on an EJB in the Navigator to open the EJB Module Editor and select EJB Local References. For additional help, click the Help button or press F1.
