We have used WildFly 8.1.0 in the book. Download WildFly 8.1.0 Final from http://wildfly.org/downloads/. In some of the chapters, we have used MySQL 5.6 Database-Community Edition, which can be downloaded from http://dev.mysql.com/downloads/mysql/. You also need to download and install the Eclipse IDE for Java EE Developers from http://www.eclipse.org/downloads/. Eclipse Luna 4.4.1 is used, but a later version can also be used. Also, install JBoss Tools (version 4.2.0 used) as a plugin to Eclipse. Apache Maven (version 3.05 or later) is also required to be installed and can be downloaded from http://maven.apache.org/download.cgi. We have used Windows OS, but if you have Linux installed, the book can still be used (though the source code and samples have not been tested with Linux). Slight modifications may be required with the Linux install; for example, the directory paths on Linux would be different than the Windows directory paths. You also need to install Java for Java-based chapters; Java SE 7 is used in the book.
