Re: not writing?

[Jason Lea]

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,
