In persistence.xml I have got:
<persistence-unit name="my_persistence_unit" transaction-type="JTA">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=my_persistence_unit)</jta-data-source>
<mapping-file>META-INF/orm.xml</mapping-file>
...
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.archive.autodetection"
value="class"/>
<property name="hibernate.enable_lazy_load_no_trans"
value="true"/>
<property name="hibernate.connection.isolation" value="4"/>
<property name="hibernate.connection.autocommit" value="false"/>
</properties>
</persistence-unit>
</persistence>
I have got the two Karafs with my programs and then I've added the Cellar
and Cellar-DOSGI features. Next I've put both instances into one group (not
default).
