How about you try this?

def create(name, connectionInfo, ...):
    from configure_server_foo import AdminConfig
    AdminConfig.create('DataSource')

This way, jdbc.py won't try to import configure_server.foo until 
create() is called.  By deferring that import, you should be able to 
avoid the circular import problem...
