Michael, I know you said PayPal, but I'd offer that GWT Stripe<https://github.com/ArcBees/gwt-stripe>has been working pretty well for me. The nice thing about Stripe it is that it's completely transparent to the end user, so it looks like you're handling the payment processing, and you don't have to force your user to leave your site and login to PayPal. It's also great that only the creditcard and expiration are the true required fields, making mobile checkout a lot easier.
The only annoyance to this kind of checkout process with GWT is managing the state transitions. Please correct me if I'm wrong, but there is no Spring WebFlow equivalent in GWT where you can setup State A, B, C, D and all the rules for transitions between them to ensure if a customer is at checkout stage D and hits back, you properly handle the transition back to stage C (or prevent it). I had to write my own workflow stage router for this piece of the process. Sincerely, Joseph -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
