All,
I too have recently passed SCJP2. I recently attended the Sun Technical Conference at London and was very impressed by the J2EE technology. The link http:/java.sun.com/j2ee contains loads of information. The J2ee blueprints let U know the design principles of J2ee. It also has a Pet store application that implements the design principles explained.
The following link http://developer.java.sun.com/developer/onlineTraining/J2EE/Intro/index.html is a step by step tutorial about J2ee. I found it a good learning tool for beginners.
Another good link is http://java.sun.com/j2ee/j2sdkee/techdocs/guides/ejb/html/DevGuideTOC.html which is a developers guide to J2ee.
I guess as beginners it is absolutely essential to understand how the various technology hang together and then focus on a specific technology. I am saying this as many people consider J2ee to be synonymous with EJB.
Would love to hear feedback from other beginners and experts

Hi Harpal
I have not installed the petstore yet. But have colleagues who have done it without any problems.

Hi,
I was wondering if you could tell me what software do I need to get started with J2EE? I mean I already have the J2EE SDK but what else do I need and how should I organize them (what do I connect with what)? I have ready quite a few tut's and none of them say what I need. I would really appreciate any input.
Thanks
Jay

Saw this thread in a search, and downloaded the PDF file. I got as far as Chapter 5, but when I tried to run the lab, I got the error :
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 29 in the jsp file: /bonus.jsp
Generated servlet error:
c:\j2sdkee1.3.1\repository\D-XXC27T67FM2WM\web\JSPRoot\bonus$jsp.java:63: Class org.apache.jsp.JBonusBean not found.
JBonusBean jbonus = null;


Seems like the JSP cannot locate JBonusBean.
Can anyone help ? I'm using
JDK 1.3.1_03 and
J2SDK Enterprise Edition 1.3.1
thanks

you must import the class in jsp file if the class is in the unnamed package.
So add this line in the jsp
<%@ page import="JBonusBean" %>
and I think it will work fine
