Re: not writing?

[Kris Schneider]

I doubt JSTL will be any happier with a class that's trying to be both a 
Map and a JavaBean:

<%@ page contentType="text/plain" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<jsp:useBean id="map" class="java.util.HashMap"/>
<jsp:useBean id="obj" class="java.lang.Object"/>
map.class: <c:out value="${map.class}"/>
obj.class: <c:out value="${obj.class}"/>
<c:set target="${map}" property="class" value="Employee"/>
map.class: <c:out value="${map.class}"/>
Produces:

map.class:
obj.class: class java.lang.Object
map.class: Employee

I have read about people having problems getting or setting a bean which 
does not fit the bean specification.  In that case the Cart object would 
also need a setSubTotal(double dbl) method, even if it is not used eg

public class Cart extends HashMap {
   private double subTotal = 400.00;
   public double getSubTotal(){return subTotal;}
   public void setSubTotal(double dbl){subTotal=dbl;}
}
This could be the problem because the bean:write would expect a bean, 
but the <%...%> is just accessing an object's method.

Also the way to access maps in struts is object(value) eg <bean:write 
name="cart(abc)"/>

Which is roughly the same as <c:out value="${cart.abc}" />

These should perform the following:   cart.get("abc")

Here's the bean:

public class Cart extends HashMap {
   private double subTotal = 400.00;
   public double getSubTotal(){return subTotal;}
}
Here's the Java:

session.setAttribute("cart", new Cart());

Here's the JSP

<bean:write name="cart" property="subTotal"/> // no output?
<%= ((csp.Cart)session.getAttribute("cart")).getSubTotal() %> // works,
writes 400.0
Here's the problem

<bean:write> isn't producing any output, but

<%= ... %> is...

Any ideas are greatly appreciated.

Thanks,
