How can I start my study in J2EE?

I�m a little confused because there are many things about J2EE (Concepts and Technologies).

I have this book The J2EE Tutorial Second Edition, but I am not sure if I should start using it!

Hi Bruno-
Well, since you asked... . Raghu and I are on this forum this week to help answer questions about EJB 3 in general, and about the book we just wrote in specific. It's entitled Beginning EJB 3 Application Development: From Novice to Professional, and it was just published a few weeks ago.

Here's a comment I made in an earlier post that addresses the approach we take in this book:

I agree with Mark that the EJB 3 spec is very well written, and that it is written for a broad audience that includes app server providers (EJB container implementors) as well as EJB developers. By necessity the spec covers every intricate detail that can be specified. We aim our book squarely at the the EJB (and JPA) developer who is coming upon EJB 3 and looking for a convenient on-ramp to the techology. We elaborate on the main areas of the spec, while filtering out a lot of the advanced details, and reduce it to the most important concepts we think most EJB developers will need to get started.

Part of the trouble with a very broad technology like EJB is there is a lot of material to cover before you can see the trees for the forest. It is very difficult to jump into the advanced details of EJB and JPA before you have a good understanding of the most important concepts. Instead of wading into these advanced concepts, in many places we point readers to the appropriate area of the spec if they are interested in more depth. This way we are able to cover a lot of topics and keep the pace moving forward, without getting bogged down in the many advanced complexities that are covered in the spec documents.


Hope this helps.

Regards,
Jon

The best way that I learnt(still learning ;P ) J2EE is to divide it into parts and study one topic at a time. You can go about understanding in following sequence. It should help.

1. core Java
2. JSP/Servlets
3. EJB
4. Custom tags.
5. Struts (If using struts framework)
6. XML knowledge should help.

I know that while beginning we want to learn everything at a time but one thing at a time is the best way to lean many things quickly ;P

Hope it help!
Thanks!

1- About the first part (1. core Java):

- I�ve already done The SUN course SL275;
- I�ve worked with J2SE since march, 2006;
- I�ve studied for SCJP reading K&B�s book.

I think I had enough knowledge for the first part.

2- About the second part (2. JSP/Servlets)

- I gonna read the topics about JSP/SERVLETS in the The J2EE Tutorial Second Edition;
- I�m wondering to buy JSP/SERVLETS Head First. (What do you think about this?)

Thanks for help me!
