Amazon DevPay Int. Template

[This can be in JAVA or RUBY, but must mix with my PHP] I'm in a bind and I need just a little coding to get to the next step in my project. I'm trying to connect with DevPay from Amazon Web Services. If you know about it, cool, if not, here's their documentation (or what appears to be a good place) for Java: [login to view URL];categoryID=192 Basically DevPay is a system where customers sign up for online services (hosting etc) using Amazon's services, controlled by my server & site. I need the following code that can be easily plug-and-play with my PHP code: 1. "Activation" which basically gets the UserID from Amazon's servers when a customer signs up. 2. "Upload" files 3. "Download" files (both viewable on a browser and for download, but I think it's one in the same) 4. "Delete" files All in all it's actually REALLY easy, but I jsut don't know the first thing about Java. The code should provide the UserID as a variable I can use in PHP, and should also include a method of getting PHP variables into the java code. Please let me know in your response/bid if you've worked with Amazon Web Services before.
