See Keyspaces.java for a definition of the keyspaces. CassandraHosts manages the connections. The code uses org.imgscalr.Scalr for image manipulation It is a Netbeans maven based project. As of September 2014 this is a work in process. More needs to be done. The code is used as an example for AC32007, School of Computing, Univeristy of Dundee. I know things are still not right !
