RE: HTML / Struts Help - Summary

Jay

Thanks a lot. To summarize, here is my HTML

<!-- HTML Snippet-->
<html:submit property="btnProcess">
	<bean:message key="button.processSuspends" />
</html:submit>
<html:submit property="btnViewOrg">
	<bean:message key="button.viewOrg" />
</html:submit>
<html:submit property="btnViewProd">
	<bean:message key="button.viewProd" />
</html:submit>
<!--  End of snippet-->

and in my Action Class, I have the following
   String button_pressed = null;
   Enumeration e = request.getParameterNames();
   while (e.hasMoreElements()) {
   String param = (String) e.nextElement();
   if (param.startsWith("btn")) {
        button_pressed = param;
       break;
   }
}

Works like a champ

Thanks a lot.

the other thing I found out I could have done, was, based on the SAME HTML
SNIPPET I could have a property on the ActionFormClass called BtnProcess
(with getter and setter) and I could get its value as follows 

// in the Action Form.perform()
ViewProcessSuspendsForm myForm=(ViewProcessSuspendsForm)form;
System.out.println("From the Action Form, getProcess(), the value is
"+myForm.getBtnProcess());

// Note, the value I get from this corresponds to <bean:message
key="button.processSuspends" /> from the HTML, which is the label on the
button loaded from the resource file. It happens to be "Process Suspends". I
like the first solution better.

Anyway, thanks for all the responses and help.

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.
