Thank you Francois, I tried EclipseLink, but it still doesn’t work. I am doing
all this interactively on a fresh Karaf installation. In my case since I do
not have an actual database server, so I am using H2. I installed the
following features:
feature:install jdbc
feature:install jndi
feature:install jpa
feature:install transaction
feature:install eclipselink
feature:install pax-jdbc
feature:install pax-jdbc-config
feature:install pax-jdbc-h2
feature:install pax-jdbc-pool-dbcp2

dataSourceName=tasklist
pool=dbcp2

No data source is created, either command: service:list DataSource, or
jdbc:ds-list don't show any data source.
Trying to deploy Aries-example jar
install -s
mvn:org.apache.aries.jpa.example/org.apache.aries.jpa.example.tasklist.model/2.7.0-SNAPSHOT
Produces Error:
Error executing command: Error installing bundles:
Unable to start bundle
mvn:org.apache.aries.jpa.example/org.apache.aries.jpa.example.tasklist.model/2.7.0-SNAPSHOT:
org.osgi.framework.BundleException: Unable to resolve

[[org.apache.aries.jpa.example.tasklist.model [103](R 103.0)] osgi.contract;

I am at evaluation/proof-of-concept stage, just trying to figure out what works
out-of-the-box, so I don’t have a project created, I am just using the Aries
JPA example. It does not look good as a viable approach so far.
Best regards,
Alex soto
