Structure of the exercises

This book provides different examples structured by projects divided by part and chapter. Each chapter excluding the introduction has its own project Maven sample. The exercises can be downloaded from the link provided in the Preface of this book.

Once you have downloaded the project, you will notice a tree similar to this:

Wildfly-book
    Business-components
        Injection
            pom.xml
Persistence
            pom.xml
…
        pom.xml
  Class-loading
        …
        pom.xml
  …
  pom.xml

If you are interested only in testing the examples inside the Chapter 3, Persistence, you need only to go in the persistence folder and start the Maven commands seen before.
