How to use Eclipse ee

[Dushyant Danveer]

Hello everyone,
I am new to eclipse...
I have downloaded the latest version of eclipse 3.3 (Enterprise Edition)
Created a Web dynamic project and added a servlet to test it.
Now it is giving me error that the following imports cannot be resolved:
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

This servlet is under Demo ( my app name) ->Java Resources:src -> default package -> ServletOne.java
I know I am making some stupid mistake but I have tried everything ( checking installed jre... and other settings) and still I cannot figure out the problem!
By the way I have netbeans 5.5 installed and there I can run servlets and jsp without problems. I have Sun App server 9 installed too and jre 1.6.
Please advise what I should do so that I can start using eclipse.
Thanks in advance,
Danveer

Further to the above query should I add some .jar to the lib for it to work?
Any advise would be appreciated I have googled and checked eclipse but it looks like this is too trivial a problem to be mentioned anywhere.

Ok! made some progress... I created a new project and this time it does not give me errors which is great. so now my servlet is compiled and there is no cross sign next to it.
But...
I created a WelcomeAll.html file:

html
head
title Insert title here /title
/head
body
a href="FirstServlet" click me!
/body
/html
Note: the above html is with legal '<>' unable to insert it there....
This file is located under WebContent. Now I am trying to run this by right clicking on it and selecting 'Run As' and then 'Run on Server' then J2EE preview and the output I get is:
HTTP ERROR: 200
OK
RequestURI=/Demo//WelcomeAll.html
How do i get the html page so that I can check the servlet.
Please help on this one!
Thanks in advance,
Danveer

Thanks for the help my fellow JavaRanchers....
For those who might stumble this issue...
I fixed this problem by
1. Click on Windows -> Preferences -> Installed JRE's --> Here make sure the jdk is selected instead of jre.
2. Make sure you do a clean build: Project -> Clean and then Build Project.
3. If it is not working with the first 2 steps then run eclipse with -clean and that should make it work
