A serious doubt

I've never worked with applets, so its difficult to
compare.
My experience with servlets is that I've made some small
web
applications
using servlets. The servlet was to me the controller like
you should
use it
in the MVC or Model-View-Controller design pattern. This
pattern
divides the
work in 3 parts : the View is the collection of the JSP's
or Java
Server Pages.
A JSP is like an HTML-page with javacode in it.
The Model is the collection of Javabeans.
And the Controller takes care of it all : the controller
(read servlet)
accepts
the requests, and decides which response should be given.
Besides the MVD you've got the DAO's or Data Access
Objects.
The DAO is a class which takes care of connecting to the
database and
putting the information of the database inside the the
objects.

A servlet can do all of these functions (connecting to DB,
making
objects, showing information in HTML page)
on its own. The thing about servlets is that you can decide
to divide
the work as is
written in the MVC design pattern. You end up with a web
application
that is much easier
to maintain.

Compare this to applets : I'm sure applets can connect to a
database.
But can they leave all the work to other classes, like
JSP's, DAO's ?
If not, then you've got your answer. If you want to follow
the MVC,
use servlets. If it does not matter, you can choose.

hi,

In simple words , Applet and servlet are both java code
only.
The applet will execute from the client side after
downloaded in the
browser.
The servlet will execute the java code in server side and
outputs the
HTML which is downloaded to the Client browser.
If you are still in doubt , i can give you more explanation.

Cheers,
Ravi.

yes you are near to understanding. Better try to learn
yourself, the
you will understand it completely.

applet is just like an applicatin runs inside a browser.
just like
flash plugins etc.
servlet means its runs in the back end. ie in the server.
servlet is
for generating requests, processing user data etc. if you
are
submitting information through an applet that is received by
a servlet
in the server side and that servlet will do the process.
