I agree. But i have one doubt regarding usage of stateful session beans for the given use case.

As this requirement is related to shopping cart (online). We can assume certain default non functional requirements. If we dont use EJB's for this use case then we need to handle transactions and state on our own, where as the very basic purpose of EJB stateful session bean is this.

please validate my understanding.

I think we can expose EJB3 Stateless Session Bean as WS otherwise we can simply expose POJO as WS. This depends on the requirements. If our requirements demands using of EJB's then exposing EJB3 Stateless Session Bean as WS is fine. otherwise we will be misusing EJB, where we can acheive it using simple POJO based WS.

correct me if i am wrong.

I think there will not be any difference if you use any IDE. but some IDE's provide extra features (like, UI editor, some sort of automatic code etc ). But normally it is better to start with our own code rather than IDE is doing everything for you (if you want learn anything). otherwise i heard that, NetBeans provide better facilities compared to eclipse.

But again if you are familier with eclipse, go with eclipse, its hardly take time.

I will always suggest "JSF In Action". It will be very useful for the beginner. If you think, you are familier with some topics you can escape.

Since it has more than 1000 pages, it will take time for me to finish it.



Yes it has more than 1000 pages but again its depends on your requirement. If you literally don't want to go depth into advanced topics, it will only contains 100 pages.

Hi Sagar,

I will suggest 2 books for learning JSF from scratch.


1. JSF in Action
2. Mastering Java Server Faces



In these two, i like "JSF In Action". It is very good in terms of explanation and depth.

Hi Deepthi,

Its very easy to learn EJB 3.0 if you know EJB2.x (for basic remoting concepts, middleware services etc.). I think if you are not familier with EJB2.x, you can start easily. There will not much dependecy.

Yes. i also agree that, "EJB3 In Action" is great. Inface, all the "In Action" series books are good. We are also using EJB3 in our application. You can follow these online resources for quick learning.

Hi Shilpa,

As you see, there are couple of third party JSF implementations available in the market. Out of which some are commercial (like ORacle ADF etc) and some are open source (MyFaces, IceFaces and JBoss Rich Faces). basically these will provide JSF specification implementation and also provide some useful components (which you will not find in default JSF RI).

So if you want to start with JSF, try to start from basic JSF concepts like,

- JSF Introduction
- JSF Architecture and Lifecycle
- Why JSF is different from other server side frameworks like Struts, Spring etc.
- JSF basic Components and component Identifies
- Backing Beans/Managed beans and JSF Expression language (EL)
- How JSF will handle the Navigation
- Renderers/Validators/Convertors
- Events and Event Listeners
- JSF Messages

After tou are fine with the above concepts, you can evaluate any open source framework depends on your requirement.

You can freely download any open source third party one. According to me, MyFaces and RichFaces are the best. In my present project, we are using JBoss RichFaces.

All the Best.
