You're referring to the property as a value on the value stack, which it is
not. You'd need to either use JSP EL notation, ${myList}, or make myList a
property of the action class. I would recommend the latter, since that would
be canonical S2, and almost every single piece of documentation uses S2 in
that fashion.

You should also look at the S2 documentation wiki.

I would also be wary of tying your action code so closely to Hibernate. In
general it's considered better implementation to put functionality like this
into a service object. This allows the injection of the service object into
the action via any of several IoC methodologies and makes it easier to test
the action in isolation.
