An ArrayList object is basically a object in java. And it is perfectly
possible to store objects in sessions. A look at the HttpSession Api Doc
would confirm that point.
Maybe you are working on The Java Servlet 2.1 specification which uses
setValue() instead of setAttribute() method.
Have a nice day.
