Is e.g. Hibernate EJB3 (J2SE) dedicated jus for SE environment, do I need
an application server with enterprise beans container to Generic EJB 3.
Can I use Generic EJB 3 within simple SE application. And last question is
how is Hibernate EJB3 build, is this hibernate with EJB 3.0 API or is this
completly new implementation (so why does it have hibernate in name)...
Than you for all explanation.

Olo,

EJB3 Persistence (more specifically the Java Persistence API(JPA)) is a
specification which was created to standardize Java object persistence.
Hibernate will be one of several implementations for this standard. I'm
not sure what you mean when you refer to "Generic EJB 3". The concept of
having a specification is that compliant implementations of this spec will
be interchangeable, assuming that you have written your application to the
specification.

The Dali project provides generic tooling for EJB3 implementations, but
the implementations themselves will be persistence providers such as
Hibernate, TL Essentials, etc.

JPA is designed to provide persistence inside or outside a JEE container,
so persistence providers will generally support both of these contexts.

about those two. I'm just wondering if both can be used in simple JSE

(some tutorial:-)). I used Hibernate EJB3 (J2SE) within SE environment,
but I need to check ejb generic. So thx for any hint with this.

It appears that you are using the jsr220orm plugins instead of the dali
plugins. The two project were merged a few months ago and now you need to
be using the dali plugins found at http://www.eclipse.org/dali/. You will
have to remove the jsr220orm plugins and follow the instructions to
download the Dali plugins. I hope this clears up some of the confusion.

I can't find the ejb30.jar file. Is this within this plugin (where) or
from where I could download ejb30.jar (also other jars if necessary). It
is not mentioned about this there.

This jar is typically shipped with your persistence provider. For
example, the Hibernate EntityManager provides it as ejb3-persistence.jar
in it's lib directory. In GlassFish it's all in javaee.jar

I think there is no recommendation. AFAIK Dali will work with every EJB3
persistence provider.

TopLink Essentials is the reference implementation of the Java Persistence
API (JPA). You can download TopLink Essentials from GlassFish at:

https://glassfish.dev.java.net/downloads/persistence/JavaPer sistence.html

You will find that toplink-essentials.jar includes both the Java
Persistence API (javax.persistence.*) as well as the open source reference
implementation.
