Why we need to create an app

Although this book is about developing PrimeFaces themes, we will need a web application to actually test our designs. Also, a web application will be used to show how to integrate PrimeFaces into a web application and how components such as ThemeSwitcher are used in practice to allow a user to select their themes. Because of this, we will spend some time at the beginning creating and adding a web application to a Maven-based NetBeans project. When we start creating and using our own themes, the work that we will have done here will make it far easier to appreciate our creative efforts there.
