Another option for you to consider:

#__main__ ( I forget the script's name)
import app_config
app_config.setConfiguration(AdminConfig)

from jdbc import DataStore
  . . .etc


#jdbc.py
from app_config import AdminConfig
. . .etc


#app_config.py
def setConfiguration(adm_cfg):
   global AdminConfig
   AdminConfig = adm_cfg


The reason the import solution was breaking for you earlier was that you were 
setting up circular imports by using your main script as the holder for the 
global configuration.

By creating a special 'configuration data' module, you can use that to store the 
data, and every module that needs it can import it without worrying about 
circular imports.

Any extra global configuration properties can be added by updating the 
'setConfiguration' function.

Cheers,
Nick.
