Abstract

This document contains an introductory exercise for building a Maven-based project for modules that make use of a database and JPA. It will provide step-by-step instructions and explanations of what is being added and why. Many of these steps will become boilerplate for what we need to do for most JPA Maven modules. You go through this in detail here to provide you with exposure of what is required and why certain things are in place in the examples. It is also another chance to gain experience building a Maven project from scratch before we start leveraging templates and parent projects to hide much of the details from us.
