Tony,
The sample application we have build is an online winestore application. There is a readme.txt at the root level of the source code zip file which has instructions.
Detailed instruction for each chapter are described in each chapters along with information on how code is structured and its purpose.
All chapters come with
Ant tasks which would help to run the samples. In order to run the samples there is some setup required and this is described in detail in the first chapter of the book.
If you find any specific bugs, please do send it to us, so that we can fix it and update the errata as well.
Thanks for taking time to download the source code and requesting information.
