Brad:
I looked at the API and noticed the RequestProcessor is a 1.1 feature.. Your
solution seems nice and clear! I only have one question for you though: How
do you "connect" the subclass of RequestProcessor that you wrote with the
struts ActionServlet..? Do you have to subclass the ACtionServlet too and
then join the dots there? How do you do that? There is a " processor" method
in ActionServlet which returns the processor..but I don't see a setProcessor
method..?
thanks for posting your solution: I learnt something new today..:)
