This week's book giveaways are in the Scala and Android forums. We're giving away four copies each of Machine Learning Systems: Designs that scale and Xamarin in Action: Creating native cross-platform mobile apps and have the authors on-line! See this thread and this one for details.
I lost the code for the book ... Always and I mean ALWAYS back up your hard drive! I had kept the book code on my old PC because my copy of XMLSpy only works on PCs (I use a Mac). I'm still trying to recover after a worm or wear-and-tear or something made the PC stop working. It won't even boot now.
I did test the JAXR code a lot. In fact, I ran the code through the ringer twice so I'm not sure why you are having problems. That said, the UBR registries never did behave exactly as expected so maybe there was a change.
Anyway, I haven't had time to rebuild all the code for the book yet. If anyone gets a start on this I'll be happy to open source it.
