JSF with EJB

Question

Hi,
I am new to JSF. I was wondering if anyone can shed some light on how to use JSF in J2ee environement? Will it be ActionListener's responsibility to update the model (communicate with EJB's)?
Any help will be highly appreciated.
Thanks,
Paresh

PareshThere are of course many ways to address this
question.
I susspect the most common will be an Action's invoke
method calling methods on a Session Facade [Core J2EE
Patterns].
So for example
public String invoke() {
// get myHome from a Service Locator [Core J2EE
E Patterns]
MyFacade facade = myHome.create();
facade.doTheBizLogic(...);
facade.remove();
Hope this helps.
-bd-This is indeed the sort of pattern that I expect will be quite popular. The nice thing is that it works for business logic implemented as EJBs, or as POJOs (plain old Java objects), or any other way that you like.
From an architectural perspective, you'll do yourself a favor by isolating the functional part of your business logic into classes that do not depend on any given UI technology (i.e. the process of adding a new order for a particular customer is the same whether it's done in a client/server app based on Swing, a web application based on JavaServer Faces, or a web service based on JAX-RPC). Design your business logic so that it can be reused in any such environment.
