The SCEA certification does not go into so much detail on EJBs as SCBCD. Also for personal satisfaction as SCBCD is the only Sun Java certification that I don't have (even though my SCJP and SCWCD are from older versions of the exam).
Besides I already bought the voucher and I don't want to waste it.
What do you guys think about the ejbcertificate.com mock exam? Is it harder, easier or at the same level as the real exam?
I am using Weblogic 8.1 SP2 and I have deployed an Enterprise Application in an Exploded Archive Directory using the Split Development Directory Structure.
When I make a change to a Servlet and compile it in my IDE(Eclipse), the change is made automatically to the application, that is, all I have to do is to click "refresh" on the browser and I will see the change.
But when I make a change to an EJB, this change is not reflected in the application. I have to redeploy the application in order to see the change in the application.
For example:
I have a servlet called MyServlet and an EJB called MyEjb.
MyServlet's doGet() and doPost() methods lookup MyEjb and call MyEjb's sayHello() method which returns the String "hello". Then MyServlet prints on the web page the string returned from sayHello() and finally it prints the string "the end".
If I change MyServlet to print "THE END!!!" instead of "the end" then this change is reflected in the application without the need for a redeploy. But if I change MyEjb's sayHello() method to return "hi" instead of "hello" then I need to redeploy the application or else I cannot see the change in the actual application.
The question is: Is there anyway to make the change to an EJB be automatically made in the application just as it is done with the servlet?

Where should I put third party libraries in the directory structure of my ejb-jar file?

Number 3
You only need to provide sequence diagrams for the DETAILED use cases in the assignment, i.e. 4 use cases. But that does not mean you have to have only 4 sequence diagrams. I had only 4, but I have heard of people who have made more than 4 diagrams so they could better document alternative flows.
I broke down my component diagram in 3 diagrams so it would be understandable and I explained that this was the reason for doing so.
I got 39/40 (the only point I lost in the whole assignment).
I had the same issues as everyone else in this thread. I posted a message here yesterday. Surprisingly when I got home from work I received my certificate.
I too had the same problem and got the same response.
Hi zheng shu.
I used the new book. But I see no reason why you would not be able to pass with the old one.
Could you please also tell us why you chose to take the exam (Managers required it/for fun/ to make the CV look even cooler)
Congratulations again

Hi Tony,
For part 1 I read Mark Cade's book, Mastering EJB (you can find its pdf version in www.theserverside.com) and did the mock exams from Whizlabs. I also read a few articles from the Internet. In my opinion, Mark Cade's book alone is no good at all, but for a few topics such as Security, Protocols and Internationalization it is good enough. But for me what was really essential was the mock exams from Whizlabs.
For part II I read Core J2EE Patterns and looked up a few doubts I had on UML syntax in the internet.
I had some previous experience in modelling and UML, but very little in Design Patterns. I must say that I felt very insecure about the exam.
Reading about the experience of people who passed the exam in this forum helped me a lot.
Finally, I decided to take this exam mainly for the sake of my CV.
