Re: chapter 7 compilation errors
Yes. Because the Laszlo Market application is being progressively constructed on a chapter by chapter basis, whenever you find a missing file, you need to look at the previous chapters, as this indicates that

In chapter 7, we have provided a zipcode validator and instructions on how to install it within the $LPS_HOME/lps/components/incubator/validators directory. This validator only needs to be installed once and afterwards all applications can access it.

The subsequent chapters depend on having this zipcode validator installed.
