Hi ,i convert contrller as jSp And presentation as
servlet ...will it do? if so what are advantage and
idsadvantages

Answer

If u use Servlet as presentation layer,then if u want to
modify ur program in future ,u have to shutdown the server
and class file has to be updated.

If ur usig JSP as presentation layer no need to
compile,update and shutdown the server.server container will
take care of it.

we can use JSP as controller but any one can view our code
but in servlet it is not possible.
