RC1 and MetaDataMappingFactory

Question

I'm trying to migrate from 2.5.3 to 3.0RC1.
To use only the old 2.5.3 package.jdo file including mapping information
instead of additionally my newly generated .mapping file, I've set
'metadata' as MappingFactory.
Compiling my queries, I get
kodo.jdbc.meta.MappingInfoNotFoundException: No mapping information was
found for "class thisIsMyClass".

kodo.jdbc.meta.RuntimeMappingProvider.getMapping(RuntimeMappingProvider.java:43)
     at
kodo.jdbc.meta.MappingRepository.getMappingInternal(MappingRepository.java:342)
     at kodo.jdbc.meta.MappingRepository.getMapping(MappingRepository.java:297)

     at kodo.query.QueryImpl.internalCompile(QueryImpl.java:559)
     at kodo.query.QueryImpl.compile(QueryImpl.java:523)
If I add a .mapping file with the default FileMappingFactory everything
works fine. The new mapping file was generated with kodo2migrator.
Did I misunderstand the documentation or is this an RC1-error?

Answer 1

Did you use the mappingtool to import the .mapping file created with
kodo2migrator into .jdo metadata extensions?I've mapped the mapping information back to the .jdo-files, removed the
mapping files and tried to start again with "kodo.jdbc.MappingFactory:
metadata". Unfortunately it did not work.
I'm using Oracle 9.2.0.1.0.
The only properties set next to metadata are:
javax.jdo.option.NontransactionalRead=true
javax.jdo.option.RetainValues=true
javax.jdo.option.Optimistic=true
javax.jdo.PersistenceManagerFactoryClass=kodo.jdbc.runtime.JDBCPersistenceManagerFactory
If I add the property
kodo.jdbc.SchemaFactory=dynamic
to prevent schema synchronization everything next to a bug I'll report
later works fine. I can read + (partially) write to the database.
Here's the stack trace, the .jdo-files come below:
kodo.MetaData :INFO: Parsing metadata resource
