You can create a wrapper class around the session object that intercept calls to setAttribute() and getAttribute() then using JBossSerialization serialize your objects before writing them to the session and deserialize them on return. Also, make sure that your wrapper class is thread safe so you won't get thread contention in there and would be a bottle neck in your application.
