hi guys,

It is recommended that if we are using servlet's

public void init(ServletConfig config) throws ServletException method
for initialization

then we should use

super.init(config) ;

as a first line in the code..like as below.

public void init(ServletConfig config)
throws ServletException {
super.init(config);

}

if anyone has idea then pl. let me know exact reason why i should need
to call super.init(config)..

Thanks and Regards,

To save the ServletConfig parameter so that the getServletConfig()
method can return the value (this is implemented in
GenericServlet.init()).

This is all covered in detail in the JavaDocs for GenericServlet and
HttpServlet - anybody serious about servlet development should have
them on hand.
