[b]Hibernate version:3

As Hibernate can be a layer between Struts Action and database,
is it true that using Hibernate is equal to using ejb?

I should not say "equal to".
should be "more or less the same"

Does Hibernate function "more or less the same as" ejb?

Is Hibernate 3 the same as EJB 3's persistence spec or EJB 2.x entity beans? I assume that is the question.

Well, if you look at it from the 50,000 foot view that these are mechanisms to help you store and retrieve info with a relational database then yes, they are the exact same thing.

If you look at it from the standpoint of does Hibernate, EJB 3 persistence spec, EJB 2.x support object relational mapping then you could say

Hibernate 3 - an ORM solution
EJB 3 persistence spec - a substantial subset of Hibernate 3 capability
EJB 2.x - not ORM, more like relational objects. This isn't necessarily a bad thing, it depends on your situation.
