I've started work integrating the Cassandra code into an actual app. All the code will be available on github:
The goal of the exercise is:
1: To write a Cassandra based app in Java
2: The App should use the MVC programming model
3: The app should implement a Restful interface
5: Use OpenID to facilitate logins
The code already deals with creating a new user, listing all users and listing the details for one user.
