Don't be too hard on yourself. I'm not sure how much of programming has ever
become second nature to me. No matter how experienced one gets, there's always
too much new stuff to learn.
There is no right answer. You have to work out what is best for yourself. Some
advocate an approach that starts
String loadButton = (String)request.getParameter(load);
String submitButton = (String)request.getParameter(submit);

If your jsp has a submit tag like:
shtml:submit property=OK value=Press Here if OK/
then your Action would contain something like
String okButton = request.getParameter(OK);
if (null != okButton) { ...code... }
However, RESET and CANCEL are generally something different. A standard reset

You can alway save objects to the session and application scopes. If the

is usual) then the request still exists and is passed along. So the next
Action would still have access to it. I sometimes add an attribute to

Just a comment... Looks like your method of checking the RefreshOption
property will only work if the scope of the ActionForm is session.
That's ok if one doesn't mind the use of resources.

Easiest thing is to have a propery in your ActionForm that tests whether
the combo box is empty or not. Then in your jsp you'll need to surround
the select/option tags with a logic tag of some kind, like
logic:equal name=form property=comboEmpty value=false

I'm not exactly sure of your sequence of events, but keep in mind:

ActionServlet will call that validate method. If it returns any error

Use 'validate="false"' as an action attribute to
prevent a return to the input page after a failed validate. Struts will continue
on to the action, and you'll need to decide what to do there.

I usually need 'wrap=virtual' as an attribute for my textareas. It
isn't part of the HTML spec, but it's supported in both Netscape and IE,
and it's pretty useful. I wonder how people are dealing with the lack of
