Description:If you don't have the included cd (you bought it used like I did) you will have a very difficult time following along. When I typed in the example code in chapter 1 I had to do very little to get the code to run on a modern version of java. However in chapter 2 I discovered that there is way too much code missing to in order to get the program to work. While I find that the book will still be somewhat usefull without the cd, I won't be able to get as much out of it as I wanted.
