Jpa Addressbook

Overview

The JPA based address book example serves as an insightful introduction to developing Java EE applications backed by JPA, combined with a rich UI provided by Vaadin. While it doesn't aim to be a full-fledged address book application, it successfully illustrates the integration of critical technologies necessary for crafting sophisticated web applications tailored to custom needs. With its slightly complex domain model, this example showcases how to manage relationships that are commonly encountered in real-world applications.

In addition to its primary educational purpose, this example also introduces a very basic Vaadin add-on feature—the iconic "switch" add-on—which enhances the user interface. For those new to Maven, the accompanying brief tutorial makes it easier to get started, enabling users to run the application locally or deploy it on popular Java EE servers like Wildfly or Glassfish.
