Hi Guys,
I recently had WebLogic training and this Instructor said that instead of
using the
doGet() (or) the doPost() method, over-write the service() method. He says that
if you use either a
doGet() (or) doPost() method, the WebServer has to do a POLYMORPHIC lookup on
these methods in the
service() method. This will lead to a little bit of in-efficiency. Instead if
you over-write the service() method, there
won't be any polymorphic lookup. I argued with him that the Java Servlet
specs..tell us not to over-write the
service() method, but to no avail . Any suggestions - comments welcome.
Cheers,
Amar..

Subject: Re: doPost versus doGet - DESIGN DECISION???
Personally I would suggest that both doPost and doGet call another method to
do common processing, which allows for special case processing in either
doPost or doGet if necessary.
