Where are the DB Recievers?

[Roland.Kofler]

Hi,
 
As my Chainsaw Log gave me
 
        Failed to locate Receiver class:org.apache.log4j.db.DBReceiver
        
        Failed to locate Receiver
class:org.apache.log4j.db.CustomSQLDBReceiver
        
I searched them in the CVS.
 
Hum Hum, cant find em...
Why, where, how???

Thank you a lot
