Answers-
The great thing about the validation framework is that it does both CLIENT side
validation with Javascript (if possible), but ALSO server side validation. If the user
doesn't have Javascript enabled, it will validate on the server. (Even if Javascript
is enabled, it will double check the validation on the server.)
After making the changes below, when you bring up the jsp in a browser, look at the
source. It should have Javascript in it for the validations. If not, then your
validator servlet (specified in web.xml) is probably not loading properly.
One other thing I had a problem with is the order that the struts controller and
validator were loading. In the struts controller servlet, I put
<load-on-startup>1</load-on-startup>, in the validator, I put
<load-on-startup>2</load-on-startup>. (again in web.xml)
This fixed my issue.

Isn't this required only for client-side validation via Javascript? For
example, Right now, I am simply stating that I want the required check
to be performed. In the valiation.xml file for this, there appears to be
both a java (server-side) mechanism and a javascript (client-side)
mechanism. I am not sure that we can count on javascript so I was
focused on the server-side.
