----------------------------------------
Hi Rick,
wow, that´s been fast. Thank you. I´ve tested the patch under JBoss Fuse 6.1 /
Karaf 2.3.0 and it´s working fine, no more ClassNotFoundExceptions.
Best regards,

> Using custom openjpa.BrokerFactory not working in OSGi due to ClassLoader

> Key: OPENJPA-2542

> Project: OpenJPA
> Issue Type: Bug
> Components: osgi
> Affects Versions: 2.3.0
> Environment: JBoss Fuse 6.1, Apache Aries JPA 1.0.1.redhat-610379

> For reasons discussed on the [openjpa-user
> MailingList|http://mail-archives.apache.org/mod_mbox/openjpa-users/201411.mbox/%3CCALLZsMnXPQT%2BeQB3VjYe4U05%2BgSR%2Bw37QqXGRdxdvM-kgEXdLw%40mail.gmail.com%3E]
> I need to use a custom BrokerFactory in an OSGi environment.
> My custom BrokerFactory is obviously in my own OSGi bundle, not in the
> official OpenJPA bundle. Now, due to OPENJPA-1491
> {{org.apache.openjpa.kernel.Bootstrap}} (in connection with
> {{org.apache.openjpa.persistence.PersistenceProviderImpl.createContainerEntityManagerFactory(PersistenceUnitInfo,
> Map) and
> org.apache.openjpa.persistence.osgi.PersistenceActivator.getBundleClassLoader()),
> my BrokerFactories can only live in the official OpenJPA bundle, so that my
> custom BrokerFactory is not found.
> In my opinion it would be better if
> {{org.apache.openjpa.persistence.osgi.PersistenceActivator.getBundleClassLoader()}}
> would return a ClassLoader not only delegating to openjpa´s bundle but _in
> addition_ (as a fallback) to the {{PersistenceUnitInfo}}´s bundle.
> That way one would be able to use arbitrary BrokerFactories by importing them
> if required to the bundle where {{persistence.xml}} is defined.
