From Headfirst you can study following topics.
1) Transaction
2) Exceptions
3) Security Management
4) Message Driven Beans (Only conceptual part and their lifecycle, information about clients and type of subscribers supported.)

Make sure you refer to corresponding annotations for the new version. This will be solid enough to answer any questions in this area.

Beta exam is exactly similar to any other certifications offered by Sun, you are asked to choose number of answers from Check box or option box. But still it is tough enough due to several ambiguous answers.

Apply ellimination process, that is discard the wrong options first and then amongst the best possible answers you can make a choice.

Please concentrate on

Persistence, Entity Beans, Query Language,Transactions (50% of Questions)
Session bean (15%)
Message driven Bean (15%)
Security (6%)
Others(14%)

Please have good understanding on basic concepts. Concentrate more on Entity Beans/Peristance, Query Language and Transactions

Just want to cross check here, do Entity Beans here correspond to Entity Beans in 2.1 (CMP and BMP) Or entities defined by Persistence API?

-Deepak



It does correspond to entities defined by Persistence API, the prior version exam covers more about Entity bean so there isn't much in this exam. Still I would recommend to have at least basic understanding of Entity Beans.
Hi Jianfeng,

In fact in Chaper 11, you can skip around 25-35 pages and read only part relevant to EJB exam. Read Headfirst EJB book for prior version for Security. It is oriented more towards exam and I believe it covers Security details in good depth. Mastering doesn't cover it in enough depth for exam.

I believe you can skip the Chapter 7 to 11 from Specs and read sections relevant only to EJB3.0 But some of the concepts in EJB3.0 are based on prior versions so just browse through once. Try to get in depth information about BMP, CMP and EJB-QL.
I started my studies with Mastering EJB 3.0, I found it very useful to get aquainted with the concepts. You have to study only first 12 chapters if you are focussing only for certification. In addition with this I used specs(EJB core and persistence).

I am not aware about other books but I will insist to refer to a good for Entity and Persistence, Mastering EJB is not enough at all for this !!! Rest everything you can find from this book. Also for Exceptions don't rely on this. I wonder why Mastering EJB is missing an important area like Exception Handling in EJB3.0

You can finish 12 chapters of Mastering easily in 10 days, and then use rest of the time to study Entity, persistence and Exceptions.

For transactions refer to Headfirst EJB, though its older version but transactions have not changed much in EJB 3.0 except addition of annotations. THIS IS VERY IMPORTANT.

It is good to know relationship between elements in DD and annotations and overriding rules. I would suggest to spend more time of annotation than DD. Lastly you need to have good understanding of persistence.xml

To maintain the confidentiality and quality standards of this certification I can't tell you in depth about the questions but I will definately add my experiences so that those preparing can make efforts in right direction.

Hope this helps !

All the best to you all
Dear Ranchers,

Appeared for the exam on Saturday, must say we need to have really good concentration and patience to sit for 5 hours. I was struggling to focus after 4 hours and was eager to finish.

Some of the questions were very ambiguous, and in some cases number of correct answers were more than expected. It was really difficult to decide which correct option to go for.

Number of questions were 180, I found the exam very tough. I had prepared using Mastering EJB and Specs. I must comment on the study material that you are going to use.

Please do not rely on Mastering for Entity or Persistence I would rather suggest to go for Persistence specs from Sun, agreed they are bit difficult to understand but worth.

As suggested by other exam takers, my experience is same,

1) Focus on Entities, EJB-QL (Existing features + enhancements).
2) Know annotations well.
3) You can easily get through the questions on Session beans, MDBs, Security, Exceptions, Transaction just don't ignore anything while you are studying...
4) Keep cool during exam, you have 5 hours so plan your strategy accordingly. You must finish 36 questions every hour to be in pace. Keep a watch on your pace to avoid last hour rush.
5) Don't waste time on tough questions just go ahead with the next, keep a note of those to be later if time permits.

All the best to all those appearing for it !!!

Cheers
Has anyone appeared for SCBCD Beta yet,

Please share your experiences.......

I am appearing on 16 Dec, Saturday in India so your feedback would be useful for last minute revision. :roll:

Cheers,

Hi,

I want to set a timeout when opening a connection to an HttpURLConnection.

I need an implementation of class that allows me to set the timeout even before response is generated. We want to override the default timeout.

We are using jdk1.3 so we can't use the solution provided by Java 1.4. I am aware about HttpClient by apache, but due to some architectural issues we don't want to use it.

Please do let me know if anyone has implemented similar solution or can suggest some solution.

Regards,
Sachin
