forgot weblogic server password. Help urgent!

i installed weblogic 8.1 on my system and i for got the username/password set by me during installation. I was told by my friends that unless i uninstall and install it again i cant use it.
I have done the uninstallation, however, when i install again the installation wizard does not ask me for the username and password.
Can someone help??? Is there any installation/setup file that i can refer to, to see the user name and password? Any other alternatives?

URGENT!!!
thanks!

hey, i found the answer!
Posting it here so it could be of help 4 someone else with same problem (hoping noone is as forgetful!).
It works with the default password:
username:weblogic
password:weblogic
thanks & bye!
