Mastering Java EE Development with WildFly

By: Luca Stancapiano

Overview of this book

Packed with rich assets and APIs, Wildfly 10 allows you to create state-of-the-art Java applications. This book will help you take your understanding of Java EE to the next level by creating distributed Java applications using Wildfly. The book begins by showing how to get started with a native installation of WildFly and it ends with a cloud installation. After setting up the development environment, you will implement and work with different WildFly features, such as implementing JavaServer Pages. You will also learn how you can use clustering so that your apps can handle a high volume of data traffic. You will also work with enterprise JavaBeans, solve issues related to failover, and implement Java Message Service integration. Moving ahead, you will be working with Java Naming and Directory Interface, Java Transaction API, and use ActiveMQ for message relay and message querying. This book will also show you how you can use your existing backend JavaScript code in your application. By the end of the book, you’ll have gained the knowledge to implement the latest Wildfly features in your Java applications.

Security

In this section, we will see some examples of how to make security to the servlets and configurations provided by the web.xml descriptor file.
Any enterprise component needs an application realm to configure the type of security, the location of the credentials, and the protocols to use. The default realm works with the properties files inside the configuration folder of WildFly, but it's simply configurable in the standalone.xml file descriptor of WildFly, as seen in Chapter 7, Implementing WebSockets, in the paragraph Security Realm.

File descriptor security

Now, let's see the configuration in the web.xml:

...    
<security-constraint>
<web-resource-collection>
<web-resource-name...
