The shaded area in this diagram should look a LOT like the previous diagram, especially if you remember that the Business Delegate is pretending to be the Manage Customer model.

A 6-step review:

1 Register your services with JNDI.

2 Use Busines Delegate and Service Locator to get the Manage Customer stub from JNDI.

3 Use the Business Delegate and the stub to get the “Customer Bean”, which in this case is another stub. Return this stub’s reference to the controller.

4 Add the Customer stub reference to the request.

5 The controller forwards to the View JSP. The JSP gets a reference to the Customer bean (stub) from the request object.

6 The View JSP uses EL to get the Customer Bean properties it needs to satisfy the original request.

BIG NOTE: Every time the JSP invokes a getter, the Customer stub makes a network call.
