Please take a look at the API; its a simple API designed for end  
users wanting to integrate some implementation of session management  
into a container; it hides all the details of how a session  
management solution might actually work. Make sure you read the  
documentation in the javadoc; we've tried to document it and make it  
totally obvious how to use it.

As I've said several times recently, it should be pretty trivial to  
implement the session API using WADI. Also note that there can be  
many implementations of session management depending on requirements  
- e.g. just use a database.
