Thank's Armin and Thomas.
I have added : ClassHelper.setClassLoader(myClassLoader);
And I get the same result.
Can you tell me how I can enable 'DEBUG' logging status ?
I have set jar-debug in build.xml I don't use ant ide.

Hi Thomas
I upgrade my machine from CVS this morning. The class loader problem desappear without having to use setClassLoader. Thank's for the idea.
But I sill have the following error :
STARTING DBMANAGER !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Starting TaskConsumerDB
Starting TaskConsumerDB try
[BOOT] WARN: Value "org.apache.ojb.odmg.collections.DListImpl_2" is illegal for key "OqlCollectionClass" (should be a class, using default value class org.apache.ojb.odmg.collections.DListImpl)
hmm, I think this warning is still caused by a class loader problem, because the specified class exists in source.
To get more information about repository parsing you should enable 'DEBUG' logging status for
org.apache.ojb.broker.metadata.RepositoryXmlHandler
org.apache.ojb.broker.metadata.ConnectionDescriptorXmlHandler
in the used logging framework.

I have add some debug to be sure that the problem was not classLoader. The problem arrive during *reader.parse(source) in readMetadataFromXML*
I first try to get my different repository files good, no result, then I copy all repository from test.
{orion:rcs} cp /home/rcs/Master/extern/java/db-ojb/target/srctest/org/apache/ojb/repository*.xml /home/Absynt/Compiere/mfg_scm/sbin/
{orion:rcs} cp /home/rcs/Master/extern/java/db-ojb/target/srctest/org/apache/ojb/repository.xml /home/Absynt/Compiere/mfg_scm/sbin/
And the error did not desappear.
Any idea welcome.

Hi Thomas.
In fact setClassLoader is not usable.
As ClassLoader is used inside the first call to OJB :
PersistenceBrokerFactory.defaultPersistenceBroker();
Which use it to load Configuration and Logger elements.
So when you have conflict between OJB ClassLoader and your application ClassLoader ....
Hmm, why would that prevent you from using setClassLoader ?
// this should be the very first call ClassHelper.setClassLoader(myClassLoader);
// because of this call logging and OJB will get initialized (lazy initialization)
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
Since ClassHelper does not use logging or OJB's properties, there should be no interference!
