------------------------------------
Summary: Cannot get OpenJPA 2.4.1 to work due to JPA 2.1 being
installed
Key: KARAF-4615
URL: https://issues.apache.org/jira/browse/KARAF-4615
Project: Karaf
Issue Type: Bug
Components: karaf-feature
Affects Versions: 4.0.5
Reporter: Bengt Rodehav
In order to use OpenJPA 2.4.1 both the "openjpa" (2.4.1) feature and the "jpa"
(2.3.0) features need to be installed.
However, OpenJPA needs JPA 2.0 - it does not work with JPA 2.1. But when
installing the "jpa" (2.3.0) feature, JPA 2.1 is being installed.
This has been discussed on the Karaf user list under the subject "Migrating
from Karaf 2.4.1 to 4.0.5, JPA problems".
I have, as a workaround, modified the enterprise-4.0.5-features.xml, feature
"jpa" (2.3.0), as follows:
* I have changed the version range for the peristence-api feature from
[2.0.0,2.2.0) to [2.0.0,2.1.0). This disqualifies JPA 2.1 and instead cause JPA
2.0 to be installed.
* The JPA 2.1 bundle seemed to be providing the package org.osgi.service.jpa
which is mandatory. I therefore added the following dependency:
** <bundle dependency="true">mvn:org.osgi/org.osgi.service.jpa/1.0.0</bundle>
So my modified "jpa" (2.3.0) feature now looks like this:
<feature name="jpa" description="OSGi Persistence Container" version="2.3.0">
<details>JPA implementation provided by Apache Aries JPA 2.x. NB: this
feature doesn't provide the JPA engine, you have to install one by yourself
(OpenJPA for instance)</details>
<feature version="[1.1,2)" prerequisite="false"
dependency="false">transaction-api</feature>
<bundle dependency="true">mvn:org.osgi/org.osgi.service.jpa/1.0.0</bundle>
<feature version="[2.0.0,2.1.0)" prerequisite="false"
dependency="false">persistence-api</feature>
<bundle

<bundle>mvn:org.apache.aries.jpa/org.apache.aries.jpa.container/2.3.0</bundle>
<bundle>mvn:org.apache.aries.jpa/org.apache.aries.jpa.support/2.3.0</bundle>
<conditional>
<condition>aries-blueprint</condition>
<bundle>mvn:org.apache.aries.jpa/org.apache.aries.jpa.blueprint/2.3.0</bundle>
</conditional>
</feature>
