RE: how to calculate A*B in jsp, where A and B are from nested:write

[Sri Sankaran]

There's probably a cute way of doing it with JSTL...somebody chime in, however, here's 
how you could do it with Struts tags and scriptlet

<nested:define
  property="width"
        id="width"/>
<nested:define
  property="depth"
        id="depth"/>
<%
  float w = new Float(width).floatValue();
  float d = new Float(depth).floatValue();
  float a = w * d;
%>

Subject: how to calculate A*B in jsp, where A and B are from nested:write


A newbie question:
Currently I have
<nested:write property='width'/>
<nested:write property='depth'/>
I want to calculate the area IN JSP (not to modify ActionForm) as width X depth.

I suppose I am going to use scriptlet.  How to achieve this?

Thanks.
Denis
