I'm not sure what the question means. How it's stored depends on how you've mapped the class of objects in the list.

Presumably you'd only want to select from the table where the user name and password are the same as the values on the form, no? So change your HQL. If you get a result, it means there's a user with that username and password. If you don't, there isn't, and login has failed.

That would work, but is potentially *horribly* inefficient.

What I actually meant was that you should select *only* the users from the DB whose password and username match.
