[mod_python] i have problem accessing data from database using adodb

Hello all,

I have to access data from database using adodb so I did 

Import adodb
Conn=adodb.NewADOConnection("odbc")

Upto this it works properly but when I say 

Conn.Connect("","","")

It gives error as 

[Attributrerror]: Object Nonetype has no attribute Connect.

I have Red Hat Enterprise Linux 4
Python 2.5
Mod_python 3.3.1
Please guide me through this.
