Re: not writing?

You could try something like this.

public class Cart extends ActionForm {
        
        private String subTotal;
        private ArrayList items;
	public BigDecimal getSubTotal() {

                for(int i = 0;i < items.size();i++) {
                        CartItem item = (CartItem) items.get(i);
                        BigDecimal price = item.getPrice();
                        subTotal.add(price);
                }
                return subTotal;
        }
        
        public ArrayList getItems() {
                return items;
        }
        public void setItems(ArrayList items) {
                this.items = items;
        }
        public void setItem(CartItem item) {
                this.items.add(item);
        }
        public CartItem getItem(int i) {
                CartItem item = (CartItem)  items.get(i);
                return item;
        }
}
//
public class CartItem {
        private BigDecimal price;
        public BigDecimal getPrice() {
                return price;
        }
        public void setPrice(BigDecimal price) {
                this.price = price;
        }
}
Will also work with Double and even BigDecimal although BigDecimal can 
cause issues with BeanUtils, but string always works.  Just means 
messing around doing the math and setting the value.

Kris,

Sounds good.  Looks like the answer was (wasn't) looking for.

But, I'm sure it's a great feature in a different context.

Thanks,

Subject: Re: <bean:write> not writing?
I'm pretty sure this boils down to the way PropertyUtils works.
<bean:write> will use PropertyUtils.getProperty(bean, property) to
retrieve the "subTotal" property from the bean "cart". PropertyUtils
will test whether or not "cart" is a Map (which it is) and then call
Map.get to retrieve the property value. Since you've defined "subTotal"
as a standard JavaBean property, <bean:write> (or really PropertyUtils)
won't be able to find it.

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,
