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.

Batch models

The Java Batch API (JSR 352) allows executing batch activities based on a Job Specification Language (JSL) using two main programming models: Chunk steps and Batchlets. The JSL is the XML descriptor file used to configure the processes and all its components as the steps and the Batchlets.

In this section, we will see samples of JSL and two samples of chunks and Batchlets.

Chunks

A chunk is a small part of the process working in a number of processes. It is the right actor to handle batches with large data queues. A set of chunk forms a process. It's very useful in massive boots when you need to organize your work into small steps.

For example, during a data migration, we will need to commit the operation...
