Hi Every one,
I'm preparing for the exam part 1 of
SCEA, and this week I'm studying the
EJB 3. I have book from Apress which find it very good.
My Questioon is, what we have to know and understand for the exam for EJB and JPA (
java persistence API). Do we have to master all details of Entities and their RelationShips (@oneToOne, @OneToMany, @ManyToMany..) and all the annotaion that Entities have in EJB 3 and the Mapping Entity Inheritance Hierarchies, howEjb 3 works with web services or be as Web Services etc ...
For those that did pass the exam and remember the part 1, any advice what we have to understand for the Exam ?
Your help and advices are very helpful for us and thank you so much in advance for your response,
My Best Regards,
Rania
