Decode QR Codes in AppEngine Java

I am trying to decode a QR code that is in a jpeg image that I send to AppEngine in the Java version.

I tried to use ZXing but could not. The obvious solution would be to use their Javase module, but for this you need to use BufferedImage and ImageIO, which are not available in AppEngine.

Is there an alternative solution?

PHP script example:

file_get_contents('http://zxing.org/w/decode?u=thierry-leriche-dessirier.developpez.com/tutoriels/java/creer-qrcode-zxing-java2d-5-min/images/qrcode_dvp.png');
