The hibernate jpamodelgen cannot generate entities extended from a dependency project

anhle — Fri, 21 Feb 2020 04:08:26 -0500

I have 2 project A and B. Project A dependency project B. Project B have a "ToggleableEntity" class and Project A have a "OrganizationalUnit" class

"OrganizationalUnit" class extend "ToggleableEntity" class. When I build with maven and using hibernate jpamodelgen to generate "OrganizationalUnit_" class then ToggleableEntity missed in "OrganizationalUnit_" class

The pom.xml file

The result:

The expected

nvarchar(max)

Hi All,

What is the recommendation for having column like nvarchar(max) ? what should I put in the Length value in the designer when creating Entities nvarchar(max) ? 2147483647 maybe ?

Enums in Entity Classes

Hi All,

What is the best practice in ivy to manage Enums in persistence classes ?

this example looks fine to me http://www.codejava.net/frameworks/hibernate/hibernate-enum-type-mapping-example

but how do I implemented in in ivy ? how to add @Enumerated to a field ?

Best Regards, Yordan Yunchov

Hibernate show_sql

Florian Heinrich — Fri, 04 Dec 2015 15:42:51 -0500

Hello Ivy-Team,

how can I configurate the hibernate.show_sql property? I tried to configurate it in the persistence configuration editor but nothing happened. Is there something else I have to do?

Thanks for answers

Adding additional Libraries to Hibernate, e.g. Envers

Alexis — Tue, 27 Jan 2015 17:05:26 -0500

Hello Ivy-Developers!

Envers is a powerfull Library, that comes along with the Hibernate-Package and allows auto-Auditing for entities. (History-Tables etc.)

Update:

To insert the library I did as following: Added hibernate-envers-4.2.13.Final.jar to ivy-Hibernate-jar:

designer\plugins\ch.ivyteam.hibernate_5.1.0.201409121008.jar\lib\mvn\

made some changes in the ivy-Hibernate-jar: ',lib/mvn/hibernate-envers-4.2.13.Final.jar' added to MANIFEST.MF

in pom.xml I inserted a new dependency for hibernate-envers (see pom.xml)

When inserting this library this unusual way, there are no more errors accessing the persistence.

Adding @Audited to the Entity gives no error, but no auditing happens on merge.(Wich would usualy be the case)

Merging through the EntityManager (from createEntityManager()) does not work (Nothing happens, no error)

Trying to access the AuditReader will fail on a ClassNotFoundException: org.hibernate.envers.AuditReaderFactory

// switching contextClassLoader to ivy.request.getProject().getProjectClassLoader()
EntityManager em = entityManager.createEntityManager();
AuditReaderFactory.get(em);

As I understand this has been successfully implemented in the csc project.

So the questions are: How can I integrate this library into Ivy? If not possible, is there a way to detach Hibernate more from Ivy?

Installation as described in: Guide from Hibernate

Thanks in advance!

Greetings Alexis

How to use JPA entity manager instead of Ivy Entity Manager?

Tran Cuong Truc — Mon, 22 Dec 2014 03:47:09 -0500

Hi everyone,

Currently, I need to set up and use the JPA entity manager not Ivy Entity Manager because our team want it to work with JUnit. (Ivy Entity Manager doesn't work with JUnit because of Ivy environment).

Is that possible to do so? I have tried edit the persistence.xml and try to create an entity manager but I've got the exception:
