credit card number and expiry date checking in java

In struts 1.3 , i have a payment.jsp,

• Credit Card Number.
• Credit Card Type.
• Card Holder Name.
• Expiration Date.
• CVV Number.
• Comments.

The action form PaymentForm has the validations for the creditCardNumber as

!GenericValidator.isCreditCard(creditCardNumber)

, & expairy date开发者_运维问答 to select the MM & YYYY.

my question is , On submit button Then there should be an API (standard) which should validate the credit card details and process the payments. So which api i should use ?

You will need a (payed) subscription to a Payment Service Provider and use the API they possibly provide. Usually, you will need generate a URL and make a post with this URL.
