Jpa component, persistency.xml location
Hi,
Actually i'm developping camel routes under OSGi, so i create bundles and
deploy them onto a OSGi framework with camel-core bundles on it. Everything
is ok but:
I neet to use the JPA component in order to map an entity bean to the
database, but i don't know were to put the persistency.xml. Is there any way
to tell it by a programmatic way ? If not where can i put it?

Hi,
You don't need to export he META-INF directory, as the openjpa bundle
will find check the persistence.xml for your whether your bundle export
the META-INF directory or not.
Please make sure you install a right version of openjpa bundle.
Mine is
org.apache.servicemix.bundles/org.apache.servicemix.bundles.openjpa/1.2.1_1-SNAPSHOT

i think my persistency.xml is never read because i got this error:
org.apache.camel.FailedToCreateProducerException: Failed to create Producer
for endpoint:
Endpoint[jpa://com.xxx.routecsvoracle.EntityBean?persistenceUnit=postgres].
Reason: javax.persistence.PersistenceException: Found
'javax.persistence.provider' property in the map but the value is not a
String. Found object : 'null'.
OK, so how can i export the META-INF with bnd plugin?
What is the good syntax for it? (i know it's forbidden by OSGi spec but i
think, i don't have any other choice)
Thanks.

Hi,
You just need to put the persistency.xml into your bundle's META-INF
directory (your bundle also need to export this META-INF package), and
the servicemix-jpa bundle will find this file automatically.

Yes.
BTW, there is an OSGi unit test[1] which tests the openjpa and camel-jpa
bundle.

Thanks Willem for your response;
As i'm not on ServiceMix, but i'm directly on a Felix, i don't have
servicemix-jpa bundle.
So i searched the servicemix sources a littlebit and i found the openjpa,
when i looked its code it implements SynchronousBundleListener which means
it listens for every bundle coming on the framework and reads its
META-INF/persistency.xml.
So if i just deploy openjpa, you think it's going to work and i will have my
jpa config ready to use by camel jpa endpoint?
