I need to create a shopping cart in jsp pages that works paypal. I have no experience with shopping cards, and don't have a clear vision what has to happen. I would think there would be some sort of java libraries since shopping cards are widely used, but I haven't found anything on the topic in my programming books or the web so far. Can anyone recommend or point me to some commonly used approaches or libraries? Thanks in advance.
It was incredibly easy. You just join PayPal, and then you build your links. Paypal simply asks you what you are selling, and how much. You tell it, and it gives you the HTML. You just put your HTML where you want it in your page, and the link comes up. It will also provide you HTML to show a shopping cart.
When a user clicks on your PayPal link, PayPal adds to the users cart, and when the customer clicks on the cart, they can check out.
