Is there an example somewhere that shows how to do this?  Or can someone
paste a snippet here of how to do this?  I assume a lot of webapps have the
concept of a User object.

Subject: Re: Wicket Session and threading

If you use hibernate, this is not recommended... An entity can only be
part of one Hibernate Session, and storing the instance in the wicket
session will share it across threads, and hence you'll get hibernate
exceptions.

Note that this may not be only a problem in Hibernate, but can also be
a problem in other db frameworks.

So do what Johan described and you will be safe...
