Ruby QR code decoder?

[ckundo]

I'd like to use be able to decode QR codes that people submit to my
rails app. I'm using phonegap for iPhone, so I need to create a work-
around for a native QR code reader. The best I can come up with is
having someone take a picture of the code and submit it, then have
ruby parse it.*

I've searched this forum and online, and all I can find is the zxing
library for Java. Question is:

a) is there a rails plugin or a ruby gem that can decode a qr code
image
or b) is it possible to run a java command from ruby?

Thanks for any guidance.

*yes, I will be looking into obj-c eventually, but want to prototype
asap

Eric: Why so incredulous? My point is that I'd rather prototype
something quickly for user testing before I try learn a completely new
language.

To anyone else interested: I found out how to execute java using %x|
java ...| . I think latency would be an issue in the scenario I'm
describing, but I'm going to give it a shot.

Just that in 10 months of asap you could have implemented any of:

Nothing personal, just sayin'. And yeah, there seem to be any number
of system call solutions.

Or use JRuby and RJB.

Eric, I think I see the confusion. Check http://www.ruby-forum.com/topic/198410,
you'll see that the timestamps are borked (see your reply from 10
months ago). In any event, thanks for the link.

There is nothing wrong with the timestamps. They're just European-style
DMY.
