New to Servlets/JSP

I am new to the world of server side programming. Could any one help in where to start?I don't know the diff bet' servlets and JSPs. What are their purposes? How can we use them? If you can please suggest me good books/down loadable links it would be highly useful for me.
Tks

Kumaresan,
You can download the jswdk (Java Server Web Development Kit) >from SUN from this link.
http://java.sun.com/products/servlet/README.html
A good tutorial on JSP is also there from Sun's site. http://java.sun.com/products/jsp/docs.html
Right now I am in middle of another work. I try to post some info on what are servlets and jsp latter.

I don't understand why people keep recommending the JSWDK.
As far as I know, that has not been updated in months!
Sun turned over all the servlet and JSP code to the Apache organization to do the open-source "reference implementation" of the JSP 1.1 and Servlet 2.2 APIs. Furthermore Sun has engineers actively working on the Apache project (called Tomcat)!
Go to jakarta.apache.org
for the latest implementation.
