Due to my busy work schedule, I don't have a chance to look at the SCEA 5 results.

I just noticed that I passed SCEA 5 Beta with a score of 82.5%, 132/160 in Part II and III.

At this moment, I would like to Thank Sun for giving me a wonderful oppurtunity to take part in this great exam.

All the best, Javaranchers!

Thanks
Lawrence
Hi rathi ji,

Dear All,

Couple of days before last Christmas, I took the SCBCD 5.0 beta exam. Today I found from Sun Cert manager, I have scored 96%. Actually I aimed for centum, but I think, this is Ok, given the challenging scenarios of the SCBCD 5.0 exam.

Cheers

Great effort Shoib,

Please find below my answers. I answered it as if I took the original exam -- didn't refer any notes or practiced anything , while answering these questions.

1) E. 0, 1, 2, 3
2) B. Bean instance will not be created
3) E. Stateful bean can not be timeout while in a transaction
4) A. yes
5) None of the answers are right. For stateless session beans the "Resource manager access" are available only in business method in this scenario. so the right answer should be 4)
6) E. It will throw an EJBException
7) D. By using @ExcludeDefaultInterceptors and @ExcludeClassInterceptors
8) All
9) C. business interceptor, business interceptor2, local business interceptor, business method
10) A. PostConstruct interceptor1, PostConstruct intercept2, PostConstruct
11) A,C,D,E
Hi Edvin,

That's a great input. How much you scored and what is the pass percentage?

Hi,

I guess it is because Timers can be created only via TimerService. The Stateful beans are allowed to access a Timer ( for instance obtaining it as return parameter from a stateless bean's business method). If you compare the table 4.4.1 (operation allowed in stateful beans) with the 4.5.2 (operations allowed in stateless beans) you will realize, the stateless bean methods can access TimerService in addition to Timer.

Hope this helps.

Hi,

It looks like, the provider you are using (Hibernate) is having some issues. When I tried with a similar example in Toplink ships with reference implementation of EJB Server ( Glassfish), it works for me.

Hi,

Just an idea.. If you don't want the MDB to invoke the Session bean, it means you are expecting only a certain roles to access the Session bean, In that scenario, you can specify the @RolesAllowed annotation in the Session Bean to enumerate the allowed application specific roles -- this will restrict the "anonymous" calls from the MDB.

Will that help..

Hi,

I can say both are right, since @PostConstruct is part of "javax.annotation" -- it means it can be used for any kind of callback implementation (not just for EJB). But when to comes to EJB, the specification further restricts the callback by saying it should not be final.
