Thanks for explaining what E-commerce is all about. But I'm
still confused a little bit.
When you say Amazon, Barnes and Noble use servlets or server-
side programming. I have the following questions.
1> Does that servlet use classes,objects and methods like in
applets or GUI programming.?
2> Suppose I want to specialise in Server-side programming and
JDBC what all do i need to know. Do i need to know applet
programming with all classes, objects, methods, inner classes
3> What is the difference between an applet and a servlet.

1) yes.
2) You don't need to know about applets, but you would be wise to know about inner classes.
3) An applet runs on a browser. A servlet runs on a servlet server (usually hooked up to a web server).
Don't get me started about those stupid light bulbs.
