Unable to start the Weblogic 10 server

Question

Hello all,
I have recently installed weblogic 10 application server on a Linux box successfully, and then created a domain and was trying to start the application server with the start script like
./startWebLogic.sh
I have configured the user name and password to be weblogic/weblogic.
However I received the following error, can someone please help... Thanks in advance..

But I must confess one thing here, I was able to successfully install WL 10 , created a domain and installed my application on another Linux box and I havent found the folder security under AdminServer neither the boot.properties. And that server starts and stops fine.
Thanks
