I am studing for that certification now and it was useful.
It is a little bit tricky because you didn't declared the "nil" attribute in the element. The "nillable" attribute from the XML Schema is just to say if the element can or cannot to be without a value, empty. So from my point of view only the last is right.
Hi Oguz,

You're not correct. What RMH book said is the elements would be implicitly qualified, not exactly qualified through the default namespace. You said in the elementFormDefault attribute that you want unqualified elements, so the document is correct because you didnt qualify the elements.

Dear,

I recommend you to start with Monson-Haefel book, the first chapters introduces you in the WS world, and this book will link the topics with the technologies you already know.
Its a hard task to do, because this book is huge, however nobody said it'll be easy.

Regards,

Rodrigo.
I�ll make this test in the next days. I hope to stay near from your results. Cause you was very well. Im studing the UML 2 Certification Guide.

You can buy the "SCBCD by Dr. Paul Sanguera". Its complete.
Ninety percent of your question was answered, but a piece not. You ask what is the diference between ejbCreate() method in a Session (stateless) and Entity beans. The answer is: Session stateless this method is called by the container when the container starts (it create a bunch of them) and after created its beans are putted on the pool. At the Entity the ejbCreate() is executed when the client call create on the home interface, it will get a bean from the pool and create an entity (row) on underline database. So it is much different.

Its not in EJB spec. So the answer is: not.

Hi,
components of other layers cannot invoke methods of client. The client here is the client of EJBs not communication inter EJBs.

I had surprised with JDeveloper for J2EE applications it is full and free. Better, in my point of view, than Eclipse or NetBeans. You can model the UML domain classes and it create automatically the entity beans and session beans. Great! I never saw an free tool do it.

I buy two books: Head First EJB by Katy Sierra and SCBCD Exam Study Kit by Paul Sanghera. The best is SCBCD by Paul Sanghera in my point of view, but HF EJB is good too. You can find it in www.amazon.com or www.pookbool.com.

Hello,
I think you cant use a local interface accessing from a stand alone client, because they are in diferent container.

Best regards,
The MessageDrivenBean interface haven�t the ejbCreate() method, so I think that is the problem, it just have setMessageDrivenContext(...) and ejbRemove(). The question is so tricky.

When talk about scenario-based questions is like it:

"What you must do in your environment when the number of application users increase 50% per month?"

They talk about one enterprise scenario and you answer the solution for the question.
