public class FCBaseServlet
extends javax.servlet.http.HttpServlet

A basic servlet that other servlets should extend. Keeps track of servlet loaded/unloaded counts and other statistics.

Each servlet instantiates and uses it's own SystemLogger. This is useful because per servlet/jsp log-levels can be set (via the AdminServlet)

Each servlet also stores an instance of itself in a map containing all servlets in the servletcontext (This map can be obtained via the context attribute of name ContextInit#ALL_SERVLETS_KEY). Within the map, a particular servlet is stored with the key obtained via calling: that_servlet.getClass().getName()
