I figured this one out. Man, what a landmine. BTW, good suggestions from
all of you.
Here's what I did:
In my struts config I named the form property "cart". See below
<form-bean name="shoppingCartForm"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="cart"
type="com.je.common.ShoppingCartItem[]"/>
</form-bean>
Here's the gotcha: You also have to name the "var" in the loop the exact
same name. I should have said var="cart" NOT var="item". The code works
fine now. The old code is below. To fix just change "item" to "cart". OH,
I also switched to <logic:iterate /> but that should not make any
difference.
<c:forEach var="item" items="${cartitems}">
<tr>
<td><c:out value="${item.id}" /></td>
<td><html:text name="item" indexed="true" property="unitPrice"
size="6" /></td>
<td><html:text name="item" indexed="true"
property="quantity"/></td>
<%--<td><html:text name="total" value="" size="7"/></td>--%>
</tr>
</c:forEach>
L8r all, Man I wish the JBOSS site had as good a list as this one. The
list has been a great help to me.

... and also, you're probably going to need to look into populating an empty
array or List called from your reset method. Pain in the butt, but there is
a lot in the archives about ways to handle it. For testing puprposes to
start with just give the form session scope which will avoid the problem
(but not necessarily the best thing in the world to do).
