JEE Learning Track

(Yes, it's no longer J2EE, it's been renamed JEE now!)
This early morning I read somebody asking, what is the learning track for a Java SE developer if he wants to learn the Java EE platform.

I try to list down and compile the track to learn based on my own experience:

1. Download and install an JSP/Servlet Container (recommended: Apache Tomcat 5.5)
2. Learn to deploy a simple JSP/Servlet application, like one from Sun, one from BEA, etc.
   
3. Some usage of the JSP headers
4. Try to deploy a Servlet
1. Folder structure of a simple WAR file
2. Folder structure of an EAR file
   
3. Setting up the web.xml (this is one of the intricated process)
4. Setting up the correct mapping and filter
5. (I will continue this later...)
