Greetings,
today I have completed my EJB 3.0 book(Enterprise JavaBeans 3.0, O'Reilly, 5th edition) and I have also READ all the specs. Tomorrow I'm starting with mock exams by Entuhuare.
However, my first impression is that it is theorically impossible to clear the exam: it's too huge and full of details that I can never remember all together, also .
Moreover, I have not yet faced the compatibility issues with EJB 2.x, also because I don't know EJB 2.x at all.
I would not want to study EJB 2.x, too, and I have to fix all the important details for the exam.

So, what would you suggest before (or instead of) buying the vaucher and try to clear the exam?

Thanks to everybody

try to take more mock exams before taking the real exam. also reading the experience from previous exam takers would be sufficient.

Thanks,
Today I've tried my first mock exam from Entuhuare. I got 64%, which is really poor, but I could focus on some of my problems. I've learned things that I would have never understood simply studying the specs and/or the book.

I'll keep track of my progress as a support for anybody else in my situation.

As I promised, here it's my experience progress:
Analyzing the first test result, I have understood the transaction topic more deeply. I think I could not really understand those details without the mock exam.
In general, it is a very good idea to mark the questions you are not sure about and review it even if your answer was true: the explanation is very useful an removes any doubt.

Today I have cleared the second mock exam with a score of 77%, which is better but I hope to get better results.
From this mock exam I could understand that I have not yet understood the 'Deployer', 'Bean provider', etc... rules.
Probably I'll open a new topic in this portal.

Thanks Christophe!

Well, today I have cleared my third Entuhuare mock exam. I got about 80%.
I've noticed that
[LIST]
[*]1. There are a lot of questions about roles (deployer, administrator...)
[*]2. The question that I don't mark and that I fail are becoming more rare.
This means that I fail only the questions for which I have some doubt.
It is not obvious at all.
[*]3. There are really a lot of details I'll never remember

I think a good work would be to get all the information about deployer, administrator, etc, and create a resume for all the areas.
I hoped someone had already done such a work; I had opened a topic about it but nobody has answered yet, so I'll do it for me and for the community.

1. There are a lot of questions about roles


There were a lot of questions about roles in SCBCD 1.3 too. There's a small summary of each role in Mikalai's guide, but I'm not sure this would be enough. Head First EJB for 1.3 had a nice summary for some of the roles.

Thanks, Christophe!

Today I have cleared another mock exam, with 82% score.
By these three mock exams I created a list of all the topic I still fell weak:
1. Security
2. Roles, expecially with security and managed resources
3. Details about persistence
4. The available EJBContext methods and resources availability in all cases: @PostConstruct, business methods, constructor

I'll get in depth with these points. Meanwhile, I'd like to give a look to other mock exams.
Have you got any?

Thanks

Aaahhh, that was a big topic in SCBCD1.3 too. I hate these questions.

Have you got any?


Nope, none other than those listed in the links.

Well, you are right.
Anyway, in the specs for EJB 3.0 there's a table with all the possible invocations, including the old 2.1 methods (get*Home() et similia); I don't know the paragraph, though.
I'll give a look to EJB 1.3 Mikalai's guide about that. Actually I'm trying to keep only the necessary about 1.3 specs: unfortunately, I don't know it and I prefer not to completely study it because
1. It's older
2. It's harder to use
3. Actually, I'm getting certifications for my professional culture, not for a specific project

Well, for now thanks for the mocks links! I'll try it and, as usual, I'll keep track of my impressions.

Greetings,
today I have cleared my last mock exam: 82%.
The result was not impressive, but I could understand that:
1. There are a lot of stupid details I'll never remember
2. There are a lot of tricky questions, often out of topic
3. I'll never remember 'what a method can do': the reason why is that there are some differences between stateless and stateful session beans (try to give a look to @PostConstruct method...) and I can't find a deep conceptual reason that explains that. So, I'll hope I won't find any question about
4. I don't understand the roles: I tried to study them separately, but simply I can't fully understand them. The main problem is that I can't find a general rule that explains all the roles competences. So, I'll use the same strategy at point 3.

Exam date is near...

Hy guys,
I've just cleared the SCBCD 5.0 exam with 90% score.
I'm really happy about the result, also considering that I had no previous experience on EJB. However, my good Hibernate knowledge helped me a lot.
I spent about an hour a day for 3 days a week, for 10 months = 120 hours. My main problem was I had not continuous preparation time.

Based on the experience of the exam:
1. It seems to me that xml syntax details are not required
2. I still have problem about roles, which have given me problems on security. There must be a logic that can explain all the details about roles, but I could not find it.
3. I have noticed that the exam is not so hard or tricky: instead, it asks for details that, if you haven't previously met on a mock exam or you have read in details in the specs, you can't answer to.
4. Mock exams (and expecially Enthuware) must be used as an hint to discover your lacks, and NOT a way to study for the exam. So, if you failed a question on a topic, the best thing is to review all the topic on the specs.
5. EJB 5.0 is a very clear specification, and this should happen learners.

Thanks everybody for the support.

Hi Mirko,

Amazing feat man. 90% is great and so is the way in which you prepared. Even I am facing the same problems as you..... Roles, EJB 2.x and loads of theory. I would be even happy to get around 90% as I am already exhausted just taking the mocks....haha
