So, if i get it correctly you:
- downloaded bitaddress.org's sourcecode
- generated a bunch of paper wallets
- funded the addresses on the paper wallets
This part is OK...
Now, for the rest of your story:
- how did you fund the exchange's address? Did you sweep the private key on the paper wallet, did you import the private key directly, did you use a website like coinb.in,...
BTW, was the private key bip38 encrypted?
I have created the wallet address through bitaddress.org and it generated the private keys too. I later made some Bitcoin purchase through the local exchange and now when i am trying to transfer those BTC to the wallet address(the one generated through bitaddress.org) and checked it under blockchain.info,it shows nothing to me. No transaction at all.
