Arduino Java Serial Port gnu.io.NoSuchPortException

Question

I am using serial port JAVA to Arduino.. But i get this error when i run the program.What is the my fault i am going to add Serial.dll and paralel.dll on this way C:\Program Files\Java\jre1.8.0_66\bin but i dont know where is my fault..

public class ArduinoServer  extends JArduino{

    public ArduinoServer(String port) {
        super(port);
        // TODO Auto-generated constructor stub
    }

    static int LedParlakligi=0;
    public static void main(String[] Args)
    {

        String serialPort;

        serialPort = "COM5";

    JArduino arduino = new ArduinoServer(serialPort);
    arduino.runArduinoProcess();


    }
    @Override
    protected void loop() {

        digitalWrite(DigitalPin.PIN_9, DigitalState.fromValue((byte) 55));
        delay(50); // wait for a second

    }
    @Override
    protected void setup() {
        // initialize the digital pin as an output.
        // Pin 13 has an LED connected on most Arduino boards:
        pinMode(DigitalPin.PIN_9, PinMode.OUTPUT);

    }


}

I am going to try 2 way about SerialPort first is SerialPort = "5"; Second is SerialPort="COM5";
