I started to work with openJPA and created a osgi bundle (simpleProject) based on this example, http://www.liquid-reality.de/display/liquid/2012/01/13/Apache+Karaf+Tutorial+Part+6+-+Database+Access
In karaf 2.3.0, I installed the following features & bundles: features:install jndi jpa transaction install -s mvn:org.apache.derby/derby/10.8.2.2 install -s mvn:commons-collections/commons-collections/3.2.1 install -s mvn:commons-pool/commons-pool/1.5.4 install -s mvn:commons-dbcp/commons-dbcp/1.4 install -s mvn:commons-lang/commons-lang/2.6 install -s wrap:mvn:net.sourceforge.serp/serp/1.13.1 install -s mvn:org.apache.openjpa/openjpa/2.1.1 install -s mvn:org.apache.aries/org.apache.aries.util/0.4 Then I dropped the following datasource-derby.xml (taken from www.liquid-reality.de example above) <?xml version="1.0" encoding="UTF-8"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; default-activation="eager"> <bean id="dataSource" class="org.apache.derby.jdbc.EmbeddedXADataSource"> <property name="databaseName" value="test"/> <property name="createDatabase" value="create" /> </bean> <service ref="dataSource" interface="javax.sql.DataSource"> <service-properties> <entry key="osgi.jndi.service.name" value="jdbc/derbyds"/> </service-properties> </service> <service ref="dataSource" interface="javax.sql.XADataSource"> <service-properties> <entry key="osgi.jndi.service.name" value="jdbc/derbydsxa"/> </service-properties> </service> </blueprint> And once I install my OSGi bundle (simpleProject), the bundle blueprint status remains in 'GracePeriod' and ultimately fails as shown below: karaf@root> list START LEVEL 100 , List Threshold: 50 ID State Blueprint Level Name [ 67] [Active ] [ ] [ 80] Apache Derby 10.8 (10.8.2000002.1181258) [ 68] [Active ] [ ] [ 80] Commons Collections (3.2.1) [ 69] [Active ] [ ] [ 80] Commons Pool (1.5.4) [ 70] [Active ] [ ] [ 80] Commons DBCP (1.4) [ 71] [Active ] [ ] [ 80] Commons Lang (2.6) [ 72] [Active ] [ ] [ 80] wrap_mvn_net.sourceforge.serp_serp_1.13.1 (0) [ 73] [Active ] [ ] [ 80] OpenJPA Aggregate Jar (2.1.1) [ 74] [Active ] [ ] [ 80] Apache Aries Util (0.4.0) [ 75] [Active ] [Failure ] [ 80] openjpa.examplejpa OSGi Bundle (0.1.0) [ 76] [Active ] [Created ] [ 80] datasource-derby.xml (0.0.0) >From log: 2012-10-29 12:30:05,506 | INFO | rint Extender: 3 | BlueprintContainerImpl | container.BlueprintContainerImpl 330 | 7 - org.apache.aries.blueprint.core - 1.0.1 | Bundle my.own.examples.openjpa.examplejpa is waiting for dependencies [(&(&(org.apache.aries.jpa.proxy.factory=true)(osgi.unit.name=person))(objectClass=javax.persistence.EntityManagerFactory))] It is not clear what is missing here because "javax.persistence.EntityManagerFactory" is part of feature:jpa installation.
