Hi François, thank you for in-depth explanation.
By Blueprint XML I mean: datasource.xml: <?xml version="1.0" encoding="UTF-8"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0" xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0" xmlns:tx="http://aries.apache.org/xmlns/transactions/v1.2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 https://osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd"> <bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource"> <property name="databaseName" value="ORACLE_DB_NAME"/> <property name="user" value="ORACLE_DB_USER"/> <property name="password" value="ORACLE_DB_PASSWORD"/> <property name="URL" value="jdbc:oracle:thin:@ //oracle.local:1521/test"/> </bean> <service interface="javax.sql.DataSource" ref="dataSource"> <service-properties> <entry key="osgi.jndi.service.name" value="jdbc/myoracle"/> </service-properties> </service> </blueprint> I see, I was looking at different feature name, I was referring to this feature ( that defines datasource ): <feature name="karaf-jpa-example-datasource" version="${project.version}"> <config name="org.ops4j.datasource-booking"> osgi.jdbc.driver.class=org.h2.Driver databaseName=booking;create=true dataSourceName=booking </config> <capability> osgi.service;objectClass=javax.sql.DataSource;effective:=active; osgi.jndi.service.name=booking </capability> </feature> You've updated <feature name="karaf-jpa-example-common" . I think I now know how to change my code to make it work. @Jean-Baptiste: I will watch KARAF-5850. Thank you both for the support.
