On a servlet 2.3 container, I would dispense with a form bean in this scenario, and just call request.getParameterMap() in my Action. On a servlet 2.2 container I'd still dispense with the form bean, and use request.getParameterNames() to build my own parameter Map, or just get them individually. > Zorzella Craig --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
