The input text fields should be repopulated (that's pretty much the
whole idea ;-), and all your errors should be displayed if you are using
the standard <html:errors/> tag. Just be sure the standard tokens are
defined in your application resources file, such as
errors.header=<ul>
errors.footer=</ul><hr>
In this case, your errors would be wrapped in <li>..</li> codes in your
application resources.
sql.access.error=<li>Unable to access database. Please try again
later.</li>
sql.access.empty=<li>Requested records were not found.</li>
Validate returns to the controller, which saves the ActionErrors to the
request for you (when it is not null), and then returns control to the
URI indicated by the input property.
Is your original data-entry page and the input page on the Action
mapping it submits to the same page?
