snippet from request processor:
// Process any ActionForm bean related to this request
ActionForm form = processActionForm(request, response, mapping);
processPopulate(request, response, form, mapping);
if (!processValidate(request, response, form, mapping)) {
return;
}
// Process a forward or include specified by this mapping
if (!processForward(request, response, mapping)) {
return;
