I just want to get my basics right! this statement is something that i see everywhere.
1. Both of them provide a Object view of the persistant store.
2. JDO is lightweight because it does not involve 3 interfaces ? :-) to represent.
3. Entity bean model essentially loses out on performance because of the life cycle methods that a container needs to invoke?
Can somebody confirm if 3) is one of the reasons an entity bean is slower than other mechanisms? If that is the case, can this call back specifications be refined to make it work faster?


thanks,<br />krithika

I think you have missed the following thread, in which it said that JDO and EJB are not comparable... It's interesting too...

Well, i mentioned "Entity" beans specfically and not EJB. Are'nt Entity beans and JDO primarily designed for persistance?. Yeah the post is informative but does'nt address my question though :roll:
