After entering my credit-card's holy number, I could download the jbossbook.zip file by either ftp or http access. The .zip file contains the book in pdf format aswell as the examples mentioned in the book (even chapter 11).
Strange. Yes, you're right. I had just unzipped it, went straight to the book, and then opened it from a shortcut after that--hadn't realized the examples were sitting in the folder. Egg on my face.
