QR code generation gives an empty image

Hello, this is my code. It compiles and runs successfully. But creates a jpg blank image without any barcode. Please let me know where I have gone wrong. Thank you.
import com.idautomation.qrcode.*;
import com.idautomation.qrcode.encoder.*;

public class QREncodeImage
{
public static String[] studentdata;
public QREncodeImage(String ciphertext)
{
try{
QRCode bc = new QRCode();
bc.setVersion(40);
bc.setDataToEncode(ciphertext);
barCodeEncoder bce = new barCodeEncoder(bc, "JPEG","qr.jpg");
}
catch(Exception e)
{
System.out.println(e);
}
}

public static void main(String [] args)
{
String ciphertext = "jhbdshcbdjhbckjhdbckbdkcbdksahbckdsabckhdsabckhdasbckhbdsaljkc";
QREncodeImage dmenc = new QREncodeImage(ciphertext);
}
}

Output image:-

Operating System: Windows 7

Application: JDK 1.6

Best Answer

I have run your code and gotten the result:

image

So, it must be a local issue, since my test proved that our product generates a proper image.
