What this book covers

Chapter 1, Starting with WildFly, introduces you to this new technology giving the user a better understanding of the features present in WildFly, and this chapter will also show the reader how to perform a complete installation and will supply a brief introduction on how to do the main tasks. In addition, it gives you a complete idea of what the function of each directory is and the configuration file. At the end of this chapter, you should be able to perform a basic installation and configuration for implementing WildFly.

Chapter 2, Unified Configuration, explains that a good setting is the key to get the best of an application server in several aspects such as security, performance, and availability. Many configuration details sometimes go unnoticed but are fundamental. A great example is the default installation, which has been prepared to run quickly, and without many complications. Most of the time, it ends up being an Achilles heel and can cause problems in the future. By the end of this chapter, you will be able to implement the main settings in WildFly.

Chapter 3, WildFly CLI and Management Console, gives a brief introduction to the main settings that you can accomplish through management consoles. The management console and the CLI allow the user to connect the domain controller or a standalone server that gives us the option to perform all administrative tasks; only with the CLI, however, is it possible to execute all of them. The management console does not perform all the tasks. After this chapter, you will be able to use this tool and its main functions.

Chapter 4, Modular Services and Class Loading, is based on the JBoss modules. Instead of owning the hierarchy of the most known class loading, the WildFly class loading is based on modules that have to explicitly define the dependencies on other modules. By the end of this chapter, you will be able to understand how the class loader works.

Chapter 5, Memory and Thread Pool Management, explains that application tuning, JVM, and application servers in the Java world are very important points and can directly impact a production or development environment. We will see how the memory area is divided, what the function of each division is, and many other important concepts about this subject. By the end of this chapter, the reader will be able to measure their environment more efficiently.

Appendix, What You Need to Know – Migrating from AS 7 to WildFly 8, introduces you to the major changes that occurred between servers in JBoss AS 7 application, WildFly 8, and what you need to know to perform a migration.
