Which of the following are true statements? A Servlets are not instantiated. B JSP page is translated into a servlet when it is first invoked. C J2EE specifies two types of Web components. D Servlet engines are free to retire servlets at any time. I thought B and C are correc t but the answers say that D is also true. Are Servlet engines free to retire servlets at any time. please clarify Thanks,
From what I understand, a servlet engine might retire a servlet at any time. Imagine the engine needing to free memory because it's running out of it. So it can, for example, destroy the instance of a servlet which has been used less.

Also, have a look at the servlet life cycle, it can clear a lot of doubts.
