How to understand What JPA version I'm using in EJB?
Is JPA built-in EJB?
Regards
With a Java EE 5 container, you get JPA 1.0 (specified in the JSR 220 - Enterprise JavaBeans, Version 3.0).
With a Java EE 6 container, you get JPA 2.0 (specified in the JSR 317: Java Persistence 2.0 which is now dedicated).
And if you are providing your own JPA implementation, well, it depends on the implementation and the version you provide :)
Here are some JPA 2.0 implementations and their respective versions:
EclipseLink 2.0+
Hibernate EntityManager 3.5+
OpenJPA 2.0+
DataNucleus 2.1.0+
No JPA and EJBs are not related at all, they are totally independent. JPA is not built in EJBs. The javaee-api 6 which is the JAVA EE 6 container gives you the code for EJB 3 and JPA 2.+. In order to implement EJB3 you can use weblogic or JBoss or any application container. To implement JPA you can use hibernate, OpenJPA etc.
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
</dependency>

I would like to know if Spring 5.3 and Hibernate 5.6 are compatible. The only information I found is:
Hibernate support has been upgraded to a Hibernate ORM 5.2+ baseline, with a focus on ORM 5.4.x. Please note that Hibernate Search needs to be upgraded to 5.11.6 for Spring Framework 5.3 JPA compatibility; see Hibernate JIRA.
From: Upgrading to Spring Framework 5.x
Has anyone more information about if Spring 5.3 only compatible with Hibernate 5.4 or also with 5.6?
In the case of only Hibernate 5.4 compatible, is 5.4 EOL?
Can you use hibernate 4 with Spring boot 5? I am trying to integrate hibernate 4 with Spring boot 5 since I want to use Hibernate 4 functions and API instead of 5, but I am using Spring boot 5 and getting errors such as conflicting directories between Spring boot Hibernate and custom Hibernate.
I am using Spring 5.2.3 with Spring Boot 2.2.4.RELEASE
and I want to use Hibernate 4.3.x
In the list of supported Libraries for Spring 5.x, we can see Hibernate as 5+
https://github.com/spring-projects/spring-framework/wiki/Upgrading-to-Spring-Framework-5.x
Spring 5x is compatible with hibernate 4x unless you are using it as an implementation of JPA which might not be compatible.
A suggestion would be using the latest hibernate.
I'm using spring 3.0.6 in my project with hibernate 3.3.2.GA. Can I upgrade my hibernate to the version 4.3.11.Final without any integration issues.
For more information you can check
Note
As of Spring 3.0, Spring requires Hibernate 3.2 or later.
http://docs.spring.io/spring/docs/3.0.x/spring-framework-reference/html/orm.html#orm-hibernate
As of Spring 4.0, Spring requires Hibernate 3.6 or later.
http://docs.spring.io/spring/docs/current/spring-framework-reference/html/orm.html#orm-hibernate
in this issue there were some problems with spring 3.2 and Hibernate 4.3, and according to the issue, there have been quite some changes between Hibernate 3.6 and 4.0. And Spring 3.0.6 was releaded in August 2011 (but the issue is from 2013).
So I think you should upgrade your Spring version as well if you want to use Hibernate 4.3.
From one comment in that issue:
Spring Framework 3.2.3+ fully supports Hibernate 4.0 to 4.2.x in its orm.hibernate4 package.
Spring Framework 4.0.1+ fully supports Hibernate 4.0 to 4.3.x in its orm.hibernate4 package.
We are in the OSGi world.
JPA 2.1 supports injectable EntityListner.
And EclipseLink supports JPA 2.1.
But the OSGi Enterprise Spec 4.x only supports JPA 2.0.
So it seems that injectable EntityListener doesn't work in OSGi, even when EclipseLink supports them.
Is it currently possible to define EntityListener in blueprint.xml and use them for injection? This would allow to inject OSGi Services into an Entity Listener. (Currently we need an explicit lookup using FrameworkUtil to do the lookup.)
Has anybody done so successfully and can share some hints, especially in regard to the used bundle (versions)?
Have you tried using the following maven dependency with org.eclipse.persistence.jpa.PersistenceProvider in the provider-Element of the persistence.xml? In the case of a JEE application server, the classloader would prefer libraries packaged with the deployed application by the ones bundled with the server itself.
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.5.1</version>
<scope>provided</scope>
</dependency>
I am using Hibernate 4 CR1. My application was previously using Spring hibernate support (for version 3).
I have not been able to find any information about this - is there any indication as to when (or which version) Spring will provide support for Hibernate 4?
UPDATE: Spring Framework 3.1 goes GA
You need to upgrade to Spring 3.1.0.RC1 released today:
Spring 3.1.0.RC1 Released:
Support for Hibernate 4.0 (up to date with 4.0 CR4)
As per comment of one of the guys is is involved in the spring project it seems that they started working on hibernate 4 support:
