Thank you Aurelian for this clearly stated answer.
I agree the items
1.JPA covers the topics of object mapping which are very clear conceptually, JDO has still a lot of functionalities which are not very flexible or too specific
2.JPA is much simpler than JDO
3.Hibernate support is big plus [i have doubts on toplinks contribution]
have contributed
alot in this victory [since it was a war i thought victory would be a convinient
word here:)]
and maybe
- JPA uses annotations a lot [after all Hibernate was very popular while only-XML config based so i have doubts on this]
I wish a seperate book on JPA is published.This absence creates a feeling that JPA is not a topic of interest/importance.
As far as I can see the JPA topic is covered in EJB/Hibernate books but a dedicated JPA book is missing.
A book titled Pro JPA is coming as far as I can see from amazon.
