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

2003-02-13 Thread Pani, Gourav 
you could use a math taglib and do it without using scriptlets.  i don't
know of one since we don't use any, but i am sure one would be available.

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

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;
%

I'm not familiar with the nested tags, but suppose you were using a
struts-el text tag, you could do like so:  html:text value=${width *
depth}/
I'm guessing you can do something similar in the nested tags.

...ah!  Much cleaner.

No, I don't think there's a nested-el

Sri
P.S.
I'm sure you meant html-el:text value=${width * depth}/

Thanks for your reply.  I believe this approach works.  However I received
exceptions:
java.lang.ClassCastException: java.lang.Float...
I am looking at bean:define to dig the bug out.

The approach resolves the problem.  Just a tiny notice, type should be
defined.
nested:define
  property=width
id=width type=java.lang.Float/
Thanks.
