is it necessary to learn them for the exam? (@Table, @Basic, @Lob)
because aside of @Id and @Embeddable i don't see any other in the objectives...

This is what I think. Even it is not appeared in the objectives, you have to learn them for the exam.

I don't think that the exam will ask only about @Id and @Embeddable.

Hi, people
Even if the @Id and @Embeddable are not explicit appearing on the exam page you still know how to use them because you need to understand how the JPA is working. Maybe there are some question where the answer relay on the understanding of the JPA but they not refer explicitly this @Id and @Embeddable. Something like : how many kinds of pk mechanisms are available in JPA ? 1,3, 5, none.
More, don't forget the real life - the certification does not helps you to provide solution if you don't understand understand the basic principles.
of course i'm going to learn them all. this is like the 3rd
time i read the 8 first chapters of "Pro EJB 3". (tough i
didn't think of SCBCD the first time)
it's just that after i answered wrong 2 questions in SCWCD
because i didn't remember exactly a setter method in the
Cookie class and other rarely used methods (and damn
the exam can be tricky in this kind of question) so i just
want to know what i have to memorize beside of all the
XML i already had some bad time memorizing them

Here I give you right, I also done the SCWCD, and this was quite detaliated in the API, I find the SCBCD easy - from this point of view.
i just noticed this objective:
Describe the use of annotations and XML mapping files, individually and in combination, for object-relational mapping. what does it mean? we must know every XML mapping tag??

I think so, to be a Sun "Certified" BCD. I think we need to know every annotation and XML tag for JPA.
of course. but i'm also complaining about the tricky question
they love to put regarding XML tags...

From what I have seen at the exam, you actually don't have to learn all the JPA annotations and their attributes, the questions are more about the logic these annotations represent, not their detailed api. Also, for the XML, I didn't learn it by heart, I just skimmed through it. I had earlier experience with some elements (ejb-ref, resource-ref, and so on) from SCWCD, but this exam did not require me to drag & drop various element and attributes. The questions always had the right XML markup, and the questions are asking about the logic, not the syntax. At least that's what I had...
