Need Help: Errors while running FibonacciExample

Hi,

After successfully compiling the example code
FibnacciExample.java, I
tried to run it, I get the following error, let me know how
to solve it:

java FibonacciExample

Is it require to place .drl file in the same directory as
that of the
source code ?

Thanks,
