Ok, I made some progress (I guess) I am no longer getting the original error:
java.lang.ClassCastException:
org.apache.openjpa.persistence.PersistenceProviderImpl cannot be cast to
javax.persistence.spi.PersistenceProvider
I added my own version of the jpa feature, in which I substitute the line
<bundle
dependency="true">mvn:org.eclipse.persistence/javax.persistence/2.1.0</bundle>
With:
<bundle
dependency="true">mvn:org.apache.geronimo.specs/geronimo-jta_1.1_spec/1.1.1</bundle>
Which results in:
<feature name="aries-jpa2”>
<capability>
osgi.service;effective:=active;objectClass=javax.persistence.spi.PersistenceProvider
</capability>
<bundle
dependency="true">mvn:org.apache.geronimo.specs/geronimo-jpa_2.0_spec/1.1</bundle>
<bundle
dependency="true">mvn:org.apache.geronimo.specs/geronimo-jta_1.1_spec/1.1.1</bundle>
<bundle
dependency="true">mvn:org.osgi/org.osgi.service.jdbc/1.0.0</bundle>
<bundle dependency="true"
start-level="30">mvn:org.apache.felix/org.apache.felix.coordinator/1.0.2</bundle>
<bundle
start-level="30">mvn:org.apache.aries.jpa/org.apache.aries.jpa.api/${aries.jpa.version}</bundle>
<bundle
start-level="30">mvn:org.apache.aries.jpa/org.apache.aries.jpa.container/${aries.jpa.version}</bundle>
<bundle
start-level="30">mvn:org.apache.aries.jpa/org.apache.aries.jpa.support/${aries.jpa.version}</bundle>
<conditional>
<condition>aries-blueprint</condition>
<bundle
start-level="30">mvn:org.apache.aries.jpa/org.apache.aries.jpa.blueprint/${aries.jpa.version}</bundle>
</conditional>
</feature>
Now, in my own feature, I have:
<feature>aries-blueprint</feature>
<feature>jndi</feature>
<feature>jdbc</feature>
<feature>transaction</feature>
<feature>aries-jpa2</feature>
<feature>openjpa</feature>
<feature>pax-jdbc-mariadb</feature>
<feature>pax-jdbc-config</feature>
Among others. Now my bundle fails to start:
Status: GracePeriod
Declarative Services
Blueprint
5/11/18 2:14 PM
Missing dependencies:
(&(osgi.unit.name=responderPersistenUnit)(objectClass=javax.persistence.EntityManager))
There are no errors in the log, just this unresolved dependency.
Any idea about why my persistent unit is not being registered?
Best regards,
