How to install Hibernate 5 into Apache Karaf v4

Question

I've installed Apache Karaf v4.03 and queried the list of available features for Hibernate, as listed below. Unfortunately, I am using Hibernate v5.

hibernate                     | 3.3.2.GA         |          | Uninstalled | enterprise-4.0.3         | Hibernate 3.x JPA persistence engine support
hibernate                     | 4.2.15.Final     |          | Uninstalled | enterprise-4.0.3         | Hibernate 4.2.x JPA persistence engine support
hibernate-envers              | 4.2.15.Final     |          | Uninstalled | enterprise-4.0.3         | Hibernate Envers 4.2.x
hibernate                     | 4.3.6.Final      |          | Uninstalled | enterprise-4.0.3         | Hibernate 4.3.x JPA persistence engine support
hibernate-envers              | 4.3.6.Final      |          | Uninstalled | enterprise-4.0.3         | Hibernate Envers 4.3.x
hibernate-validator           | 5.0.3.Final      |          | Uninstalled | enterprise-4.0.3         | Hibernate Validator support

I am unable to find instructions for installing Hibernate v5 into Karaf v4. Are there published instructions for performing this task, and perhaps a downloadable features file?

Answer 1

Hibernate 5 already provides a feature that is also available from maven central. Recent karaf versions provide a nice shortcut to install such features:

feature:repo-add hibernate 5.0.5.Final
feature:install hibernate-orm

So there is no need to manually download the hibernate zip. If you build your own feature that needs hibernate 5 then you need to provide a element in it that points to the full hibernate feature url.

mvn:org.hibernate/hibernate-osgi/5.0.5.Final/xml/karaf

Answer 2

Run the following commands on Karaf shell to get Hibernate 5.1.0.Final working on Karaf 4.0.x:

feature:repo-add mvn:org.hibernate/hibernate-osgi/5.1.0.Final/xml/karaf
feature:install hibernate-orm

Answer 3

Latest hibernate-release comes Karaf ready already:

If you download the hibernate-release-5.0.5.Final.zip from hibernate's page (http://sourceforge.net/projects/hibernate/files/hibernate-orm/5.0.5.Final/hibernate-release-5.0.5.Final.zip/download) and decompress the file, you will see an osgi folder. There you can find an already prepared feauture: hibernate-osgi-5.0.5.Final-karaf.xml. You can just copy it to Karaf's deploy folder and then execute:

feature:install hibernate-orm

It should be installed without any problem.

Another way to install hibernate 5.0.5 feature is to add a repo to features with the command:

feature:repo-add command.

Here you can see the list of hibernate's features and the one I have installed:
