This lesson is an overview of the Java EE architecture, concepts, components, and terms that will be covered in detail in the remaining lessons of this book. The goal of these lessons is to give you an understanding of how to approach the development of Java EE applications by showing you how to build small applications rather than making you read the 1,000-page manuscript that would otherwise be required for detailed coverage of this subject.

My task is to help you in making that decision and getting you started in the quickest possible way. Oracle’s white paper "Introduction to Java Platform Enterprise Edition 7"  is a good complement for this lesson. If you start browsing ...
