Don't mind for the silly questions!

Hi,
I'm completely new to this server side programming. But I know what is this. I'm good in javascript but now it is time for me to move on to server side scripting. But, I want to pose the questions regarding this.
1. what are these JSP,J2EE,EJB,STRUTS,..?
2. How they are different?
3. Where they are used?
4. How they are useful?
I know there are countless sites. But, I want what are the best sites for JSP,EJB,J2EE,... like w3schools or ehcoecho.com for HTML,JS,CSS,..
Plzz let u clarify all my doubts.
Thanks in advance,
Narendranath,

First and most important point - JSP,J2EE,EJB and STRUTS are nothing to do with JavaScript, serverside or not. Your questions are very basic stuff, so I won't answer them here - it would take too long, and is most likely to confuse not enlighten. I would recommend you read through the tutorials on Sun's site. And perhaps also Bruce Eckel's "Thinking in Enterprise Java" which is avaliable free online (google for it).
However, in your list of the technologies you already know you don't included Java. If its the case that you have not yet learned to program in Java, forget J2EE and go learn that first. There's plently of resources on Sun's site. Good luck.

java.sun.com has a decent intro for J2EE with sample code.
Please refer to that to get answers to your basic questions.
You can always use the search button on the forum to search if your questions are already answered before.

One of my favourite books is "core servlets and Java Server Pages" from Marty Hall.
Marty has also got a web site at http://www.coreservlets.com.
You can download the first edition of his book in pdf format.

Thanks for all your suggestions.
Narendranath.
