Validator

Thanks for ur quick response.I want to know how to validate the a/c no.(Something like for validating a credit card no. we r having a formula.). Is there any formula for validating an a/c no. using either struts validator framework or Form validation method.

Give me the general validation formula or technique for validating an account no. either thru struts validator framework or form validation methods.

How can you have formula for validation of a bank account number ?Hello ?Each bank follows its own numbering standard. The only way can be via access to the centralized/distributed databases of the banks.
