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.

Working with Dependency Injection

Dependency injection is a very important design principle for working simply and at the same time with major security. It lets us write a very simple code to test. Java uses this principle since Java EE 5 through the CDI specifications.

The first Java frameworks to host this technology were the following:

  • Seam: Firstly, it was a set of utilities to work better with web applications. Next, it was discontinued and integrated in the Java EE 5 specifications; now it represents the main standard that a developer must use.
  • Spring: This was the first Java dependency injection framework born exclusively for complex Java applications. Now it is an evolved set of plugins where you can build anything through dependency injection. It remains an alternative to Java EE.

Contexts and Dependency Injection (CDI) is a set of annotations and services that make...
