Overview of this book

<p>NetBeans has several features that greatly simplify Java EE development, but with many features and great flexibility, Java developers can become overwhelmed by the options available in NetBeans. This book provides step-by-step recipes that show you how to take control of the environment and make use of these features to make your enterprise Java application development more efficient and productive than ever before, so that you can concentrate on the important parts of your application.<br /><br /><em>Java EE 6 Development with NetBeans 7</em> takes you through the most important parts of Java EE programming and shows you how to use the features of NetBeans that will improve your development experience with clear, careful instructions and screenshots. It will show you how to use NetBeans functionality to automate many of the tedious or repetitive tasks frequently encountered when developing enterprise Java applications, freeing you up to focus on the business logic specific parts of the application. As well as showing you time-saving tricks, keyboard shortcuts, and other productivity enhancements possible with NetBeans, it will take you through the major Java EE APIs and how to get them working in the NetBeans environment.</p> <p>While focusing on NetBeans features, you will learn about developing applications using the servlet API and JSPs, including taking advantage of JSTL and developing custom JSP tags. Developing applications that take advantage of JavaServer Faces is also covered in detail, including how to generate standard JSF applications from an existing database schema. The book also covers how to easily develop elegant JSF applications by taking advantage of the PrimeFaces JSF 2.0 component library that is bundled with NetBeans.</p>

In most cases will want to use the JSF 2.0 framework as well, since typically CDI applications use JSF as their user interface component framework.

Clicking on the Enable Contexts and Dependency Injection checkbox has the effect of creating a file called beans.xml and placing it in the WEB-INF directory of our web application. The generated beans.xml file looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
</beans>

When our application is deployed, the presence of this file indicates to the...
