Where to store a Servlet's singletons?

Question

If my Servlet class uses a singleton (such as a manager class), where should it be stored? The servlet itself, or in the ServletContext?

Can a servlet container create more than one instance of my Servlet class to handle requests?

Answer 1

It is certain that there will be only one instance of a Servlet. But still, it's better to store it in the ServletContext. Thus it will be accessible from other servlets as well.
