HTML / Struts Help

["Mattos, John" <jm...@Indemand.com>]

Hi.

I have a form that can be submitted by three different buttons, for example
the buttons read

(Button Labels)
Process
View by Org
View by Product

What I want to do is in the Action Class handling the submission, find out
which button was pressed, and act accordingly, whether it's an actionForward
(in the case of the "view" options) or kicking off another process (as will
be done by the "process" button)

So, how can I figure out what button was pressed in that Action class? Is
there a way to do that?

You would do it the way you'd do it an any web application.

Here's how I do it:  All my button field names start with "btn".  I would 
name these buttons btnProcess, btnViewByOrg and btnViewByProcess (or 
something similar).

In my perform method, I'd put code like this:

   String button_pressed = null;
   Enumeration e = request.getParameterNames();
   while ( e.hasMoreElements() ) {
      String param = (String)e.nextElement();
      if ( param.startsWith("btn") ) {
         button_pressed = param;
         break;
      }
   }

At this point, button_pressed tells you the name of the button that was 
pressed.  I have a utility class that has this code in it and I use it 
everywhere.
