Prevent auto screen locking - Java

My first job was at an IT company where they used to have a company policy wherein they lock your PC after every 3 minute. The usual excuse was Information Security. Just imagine, every-time you have to take a leak, the PC would just lock itself up. The situation was exasperated because of another thing, the password policy, which demanded every password to be 

1. At least 8 character long.
2. At least one number.
3. At least one lower-case alphabet and one upper-case alphabet.
4. and at least one special character.

Now, all thing rules made the remembering of password a bit of a hell and on top of it was the 3 minute locking rule.

That was the time when I decided to do a bit of mischief and code a software which will do the task of moving the mouse, which would effectively prevent the desktop from locking itself. I started to look for things which would enable me to do this.

That's when I encountered Robot, a class Java provides since J2SE 1.3. This class acts like a simulation tool for various UI components ranging from keyboard to mouse.

My tool was ready within a day or so...and I have recently posted the same in Google Codes.
