Or use an AJAX piece of functionality instead of hidden frames. -----Original Message----- From: Nitesh [mailto:[EMAIL PROTECTED] Sent: 16 June 2005 06:18 To: Struts Users Mailing List; Richard Reyes Subject: Re: [OT] Validating email addresses
Richard, JavaScript validations are majorly done on client side and so it would be possible to do a actual validation of the email addresses. The JavaScript email validations mostly will check whether the email is in a valid format. (i.e. even [EMAIL PROTECTED] would pass a validation) If you have to do a whois validation the best would be to use the struts validator framework. This gives you a two-pronged validation - both client side as well as server side. The clientside Javascript validation ill check if the email is of valid format. You could probably override the server side validation to actually plug-in the code to validate with whois. The other option would be to have a hidden frame, while validating the email address, use the hidden frame to redirect to a JSP or servlet which validates the email with whois and prompt the user accordingly.

Any suggestion on proven downloadble javascript components would be very much appreciated. I might just code for the domain name validations. Can I get the valid list from whois.org?
