What's the implementation of ctx.setLoginID(foundUser) look like?
I should look something like this:
getRequest().getSession().setAttribute(USER_KEY, currentUser);
It basically is exactly that. The MyActionBeanContext class (attached)
does that in a way a little closer to the examples from the book.
