Subject Re: Aries JPA: The persistence unit has incomplete configuration and cannot be created.
Date Thu, 24 May 2018 19:41:26 GMT
File:  org.ops4j.datasource-responder.cfg


osgi.jdbc.driver.name = mariadb
dataSourceName=responder
url = jdbc:mariadb://localhost:3306/responder?characterEncoding=UTF-8&useServerPrepStmts=true

user=XXXXX
password=XXXXX
databaseName=responder

ops4j.preHook=responderDB


This is picked up by PAX-JDBC and registered as a service:  osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=responder)
I want the persistence unit  to use this DataSource.

Best regards,
Alex soto

 What I am trying to do is to not  hard code  the hibernate.dialect inside the bundle, so
I can switch to a different database without having to rebuild.
