title: QRcode generation library for java 6 application
body: <p>I need a library for generating qrcode giving a string as input. I was using <a href="https://github.com/kenglxn/QRGen" rel="nofollow noreferrer">QRgen</a> but it's not compatible with java 6 so i can't use it. I searched for an alternative but i found nothing. Any suggestion?</p>
