Storing sessions

[Savotchkin Egor]

Hi all!     in the estore-bugs.txt was stated that "The beans stored in the sessions are not serializable, while this isnt an error it prohibits fault tolerance thru session clustering and persisting sessions across restarts properly.". I made all the beans serializable, the server reports no errors when restared but session are not reloaded however (I added several items in my cart and restarted the server, after that my shopping cart became empty!!).      Am I missing something obvious?
