The ServletContext object is shared between all servlets/JSPs in an
application.
getServletContext().setAttribute("<A String>", <An object>) adds an object
to the context
getServletContext().getAttribute("<A String>") gets an object
from the context which has earlier been set
getServletContext().removeAttribute("<A String>") removes an
object from the context
When the scope of a bean in JSP is set to Application, the bean is added to
the ServletContext.
