Keep in mind also that a user may navigate away from your forms on their 
own without completing the transaction, and without canceling it. If they 
then come back to your form and start the process over they would then get 
the info they had previously entered. This may not be desired behaviour. 
So, you also need to clear the session at the beginning of the transaction. 
I would do this by having a link to your form's first page, and the action 
in that link triggers clearing the slate for a new transaction to start.


On another note, if you are using EJB's, you can also handle your issue 
with using stateful session beans. I don't recommend it over the approach 
Kevin proposed, but it is possible to do it with them.
