So it's safe to say that I'm not the sharpest tool in the shed....
I was making it more difficult than needed when just trying to print out the
variable name as a literal String.... A simple <c:out value="${formName}"/>
did the trick instead of trying... <c:out
value="${requestScope[formName].map.dynaClass"/>
Thanks for your help Adam, you did push me in the right direction.
