Answer Posted / manidhar
Your superclass includes two versions of init(),one that
takes a ServletConfig and a convenience version thats no -
arg. The3 inherited init(ServletConfig) method calls the no-
arg init method, so the only one u need to override is the
no-arg version.
no law that stops u from overriding the one that takes a
ServletConfig,but if u do then u better call super.init
(ServletConfig) but theres really NO reason why u need to
override the init(SC) method, since u can always get ur
ServletConfig by calling inherited getServletConfig()
method.
correct me if am wrong
