Its on Page#102 of HFSJ.

why is there an init()method? Why is not a constructor enough for initializing a servlet?

Because init does more than just instantiating the servlet. It does all the pre-work like setting up database connection any specific configurations required for the servlet.

Also init() method gives the servlet access to the ServletConfig and ServletContext objects, which the servlet needs to get info abt the servlet config and the web app.

thanks for the reply!
