If I change my persistence.xml to this:
<persistence-unit name="responderPersistenUnit" transaction-type="JTA">
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=responder)</jta-data-source>
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=responder)</jta-data-source>
</persistence-unit>
And the configuration entries to:
<config name="org.apache.aries.jpa.responderPersistenUnit">
javax.persistence.provider=org.hibernate.jpa.HibernatePersistenceProvider
javax.persistence.jdbc.driver=org.mariadb.jdbc.Driver
hibernate.dialect=org.hibernate.dialect.MariaDBDialect
hibernate.show_sql=false
hibernate.format_sql=true
hibernate.hbm2ddl.auto=none
</config>
Then the error Is:
java.lang.IllegalArgumentException: Cannot rebind to a different database
driver, as per the JPA service specification

If I remove the line javax.persistence.jdbc.driver=org.mariadb.jdbc.Driver from
the config file above, then I get the previous error about configuration not
being completed. 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.
Also, my DataSource is already created by PAX JDBC Config and this I don’t want
to change, since I am using PreHook facility there to run LiquiBase migrations.
Any hints or examples appreciated.
Best regards,
