CANNotInitializedException

[tac]

We've been trying to get our CANJaguar code working, but it keeps returning the CANNotInitializedException.

Our code right now is

public void robotInit(){
     try {
          CANJaguar armMotor = new CANJaguar (4,       CANJaguar.ControlMode.kPosition);
     } catch (CANTimeoutException ex){
          ex.printStackTrace();
}

What the console says:
