Hi Friends,

I'm a student working in research area of Java Component security. Now I'm starting to learn more about JEE technology that contains the core component technology. I only learned J2SE before and passed SCJP. I I read the overview of JEE technology, there are so many things that I don't know where to start.

Could anyone give any advices of how to start learning JEE quickly (I mean as quick as I can)?? Any roadmaps with guides and resources are really appreciated.

Thank you very much.
Naveen.

Naveen,
As you've noticed Java Enterprise Edition consists of many pieces. I think the best way to go about it is to learn one piece at a time. My suggested order:
  • servlets/jsps - this is the most common part of JEE (If you are only going to be working with back end components, you can skip this
  • packaging structure - how things fit together and get built
  • ejb 3 session beans - basic components
  • ejb 3 jpa - optional if you'll be using it
  • ejb 3 message driven beans - optional if you'll be using it

  • Thanks very much, Jeanne. I have two more questions about this learning path.

    1) I just wonder if there are any good guides for each section. I searched on Google and found some one recommending the online tutorial by Sun Microsystems:http://java.sun.com/j2ee/1.5/docs/tutorial/doc/. The PDF file is about 1126pages. Is this tutorial good for learning?

    Otherwise I have to get tutorials for each section: Servlet/JSP, EJB3 (Session Bean, Entity Bean), any recommendations?

    2) Sun's tutorial uses the Netbeans and Sun's Application Server as development environment. Does it matter very much if I use another one. Because I want to use Eclipse and JBoss as my working environment. I don't know if there are much differences and if it's easy to change from one to the other.

    Best wishes,
    Naveen.

    Naveen,
    As far as books go, "Head First Servlets/JSPs" and "EJB 3 in Action" are both excellent, easy to read and good for peole new to the topic. The official tutorial is ok, but it's book length and somewhat dry to read.

    The tools you use don't matter if you like to explore - which is good to do in any case. If you like following instructions verbatim, you are better off using the tools the tutorial/book describe.

    Thanks for your recommendations, Jeanne.

    I'll start from "Head First Servlet/JSPs", and then "EJB3 in Action".
