> Key: OPENJPA-1918
> URL: https://issues.apache.org/jira/browse/OPENJPA-1918
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 2.0.1, 2.1.0, 2.2.0
> Environment: apache-karaf-2.1.0, openjdk-1.6.0b20
> Reporter: Wolfgang Glas
> Assignee: Rick Curtis
> Fix For: 2.1.0, 2.2.0
>
> Attachments: OPENJPA-1918.2.patch, openjpa-1918.1-trunk.jar
>
>
> We are using openjpa inside an OSGi container together with
> openjpa.MetaDataRepository" value="Preload=true"
> We pass the appliation class loeader as part of our PersistenceUnitInfo
> implementation by returning it from PersistenceUnitInfo.getClassLoader().
> However, the code in MetaDataRepository.preload() only uses the context class
> loader and not the class loader from PersistenceUnitInfo, which leades to
> ClassNotFoundExpcetions like mentioned at the end of this report.
> A fix might be quite easily establihed by appending the return value of
> PersistenceUnitInfo.getClassLoader() to the list of claas loaders
> participating in the MultiClassLoader set up in
>
> MetaDataRepository.java:310ff
> In the meanwhile, we are additionally setting our classloader as context
> loader during the creation of the EntityManagerFactory by
> PersistenceProvider.createContainerEntityManagerFactory(), but a fix in
> MetaDatRepository.preload() is highly appreciated.
> TIA for fixing this,
> Wolfgang
