David,
Put the list of valid field values into a delimited JavaScript string at
the time of JSP page creation. Then use JavaScript to split on the
delimiter, putting it into a JavaScript array (if you have delimiter
issues, escape the values on the JSP side, delimit with a space, then
unescape on the JavaScript side). For field validation, loop through the
entries in the JavaScript array and check.

Is there a way to make the Javascript talk with the java beans at the time
of JSP page creation? That is, suppose my bean has a list of valid values
for a field. I want the Javascript to check that a field when POSTed is
one
of those valid values. How do I make the transfer of the information in
the
java bean into an Array or the like in Javascript?
