As far as I know, there's no direct Java solution for this, but it can de done with Xslt Stylesheets. I'm in the process of creating a stylesheet, which creates XML instances right now. Although it isn't completely XML Schema compliant for the moment, it still handles most schemas fairly well. It still falls short on simple types though. If you're interested, I'll post it here or send it to you.
