I have to build a on-line payment system for a web application. The requirement is like this.. For a web application, we have to build on-line payment system where the viewers should be able to pay through a credit card or something in Java.
I have no idea of it..? Can any of you help me out..
You need to sign up with a payment processing company. I don't think there are any standards in how to connect to them, so each has their own API. I would imagine that they all have example Java code available that shows how to do that. Google for "payment processing" to find such companies.
