The main use case is to be able to support JTA and non-JTA data sources from
the same bundle. I don't believe that those values can be simply injected using
the Properties map.. see below:
PU #1:
{noformat}
<persistence-unit name="pu.osgi.jta" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jndi/ds.jta)</jta-data-source>
<mapping-file>META-INF/orm.xml</mapping-file>
<class>com.company.ClassToBeEnhanced</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="openjpa.TransactionMode"
value="managed" />
<property name="org.apache.openjpa.ManagedRuntime"
value="jndi(TransactionManagerName=osgi:service/javax.transaction.TransactionManager)"
/>
....
</properties>
</persistence-unit>
{noformat}
PU #2:
{noformat}
<persistence-unit name="pu.osgi" transaction-type="RESOURCE_LOCAL">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<non-jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jndi/ds)</non-jta-data-source>
<mapping-file>META-INF/orm.xml</mapping-file>
<class>com.company.ClassToBeEnhanced</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
....
</properties>
</persistence-unit>
{noformat}
The second set of use cases is to support per-vendor extensions (ie.. setting
DBDictionary values). Some of which could be added with configuration
properties, but it gets hairy as the mere presence of certain values start
enabling certain functions, so supporting null config entries doesn't always
solve it.
See DBDictionary notes per vendor here:
