This book will demonstrate the use of freely available Java Open Source (JOS) development
frameworks for building and deploying applications. Specifically, we will focus on the JOS development
frameworks available from the Apache Software Foundation (http://apache.org) as
well as its Jakarta group (http://jakarta.apache.org).
While most books are heavy on explanation and light on actual code demonstration,
this book emphasizes approachable code examples. The authors of this book want to provide
a roadmap of JOS development tools to build your applications. Our intent in this book is not
to present each of the frameworks in minute detail. Frankly, many of the development frameworks
presented in this book could have entire books written about them.
