Thanks for the reply.

Status: head is bandaged and ready to take another shot today :-)

Just a couple questions to make sure I am understanding you completely.
My screen file is CustIndex.jsp which auto generated
pagecode.CustIndex.java.  Customer.java is a bean I built from scratch.
Are you recommending I put my listener (currently in Events.java) into
pagecode.CustIndex.java or Customer.java?  I ask because I didn't tell
you about the auto-generated pagecode.CustIndex.java. (BTW, are all
those protected methods in pagecode.CustIndex.java that are auto
generated even used? Or rather, what is their purpose?  I put
System.out.println's in each of them, but none of them get called.) 

>By the way, looks like there should be another faces-config.xml entry
for the Events.java, right?
You are correct.  I should have included that one also so you could get
the full picture.

>Anyway, this is how I would design my JSF apps, at least to get things
going.
Cool.  I will start out in this manner.  Does that mean there isn't a
way to get at my model objects from a separate object that processes
actions?  Is that where session objects come into play in some shape or
form.

Thanks for all your help Vadim, it is much appreciated.

Hi Aaron,

I guess there are various ways to design your JSF applications.
One of the simplest options is to put your ActionListener code into the
same class that backs up your JSF components, that is Customer.java.
By the way, looks like there should be another faces-config.xml entry
for the Events.java, right?

In any event, you might want to create your business object as a
separate Java class and have Customer.java reference it. Then
ActionListener will simply retrieve values of each component (name,
address, etc) since they are accessible and update your business object
with those values.

Anyway, this is how I would design my JSF apps, at least to get things
going.

Hope this helps,
Vadim.

Status: Head bleeding from wall hitting

Ok, I have just about the simplest JSF app I can think of and what just
isn't making sense to me is how I update my "model" or "business logic"
object from an action listener that isn't part of the model object.  I
am displaying an input text field where the user will enter a number.
When they hit the submit button an actionListener will get called (this
works).  But how do I fill in my Customer java object from the action
listener method?  The Customer object is registered in the
faces-config.xml as follows:

             <managed-bean>
                         <managed-bean-name>customer</managed-bean-name>

<managed-bean-class>com.wgeb.customer.Customer</managed-bean-class>
 
<managed-bean-scope>request</managed-bean-scope>
             </managed-bean>


As you can see below I am filling in the outputFormat fields with
#{customer.xxxxx} which should map to the Customer object and pull
values from it.

CustIndex.jsp:
