You
- didnt give us what tool you were using when you said "but I am able to connect through windows cmd command", because the "cmd" command definitely cannot natively talk to an oracle database
- didnt give us the version of sql developer
- didnt tell us how you were trying to connect (basic, tns, etc etc)
- didnt give us much at all....
