Your IT department has already built a subsystem for user preferences using Java SE's lang.util.prefs package APIs and you have been ordered to reuse this subsystem in your web application.

public void sessionInitialized(HttpSessionEvent se) {

User user = getUserFromCookie(se);
myFactory.setThreadLocalUser(user);
Preferences userPrefs = myFactory.userRoot();
se.getHttpSession().setAttribute("prefs", userPrefs);
}
// more code here

public void sessionCreated(HttpSessionEvent se) {
MyPrefsFactory myFactory = (MyPrefsFactory)
