Introduction to Waterken Programming

Waterken is a platform built on the Java virtual machine that allows the quick development of reliable, secure, distributed applications. In this introduction, the author will first go over the basic concepts of the Waterken platform. Then one will write two services. The first is a digital cash system. The second is a cookie store, at which one can spend digital cash and buy virtual cookies. After confirming that the store and the cash work together, one will initiate a cookie purchase while crashing the cash server and watch reliable recovery take place even though the application includes no recovery code.
