ClassDescriptor without db-connection ?
Is it possible to use the class descriptor api without having a db
connection open ? I do have a connection configured in the repository.xml
file but in certain cases I only want access to the class descriptors, not
to the database (in these cases the database might even be unavailable).

yep!
Or you can use PB.getClassDescriptor(...) too (PB use
intern the MetadataManager).
(but don't do PB.beginTransaction() this will opening
a connection)

Well, but how do I access the class descriptors without opening a
connection ? Do I use the MetadataManager for this ?

No problem, the persistent object metadata are completely
independend from the concrete connection.
