The javax JSON Library
The javax.json
library, used in Chapter 2, Data Preprocessing, is actually included in the existing NetBeans libraries. It is part of Java EE (the Enterprise Edition). If you installed one of the versions of NetBeans that includes Java EE, then you don't have to download and install the JSON library separately.
You will need to add that library to your NetBeans project though. Just repeat steps 9-10 from The Apache Commons Library section for the Java EE 7 API Library (see Figure A-34).
