MetaDataRepository.preload() ignore class loader returned by
PersistenceUnitInfo.getClassLoader()
-------------------------------------------------------------------------------------------------
Key: OPENJPA-1918
URL: https://issues.apache.org/jira/browse/OPENJPA-1918
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 2.0.1
Environment: apache-karaf-2.1.0, openjdk-1.6.0b20
Reporter: Wolfgang Glas
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
