Dear Craig,
Thank you for your respond. That does help to explain it.
It seems then, to me, the 'reflection' take place around
the "Submit" event, when "Submit" button is pressed, right ?
If, at the "Submit" time, I'd like to do all the cross-checking
of these request parameters, as well as to write their values
into a file, how could I do it ?
Would I do that in a method "setSubmit()" [no passed argument]
in the class NumberGuessBean ?
Thanks again.
