First, you need to download it to your environment. At the time of writing, WildFly has no Java EE 8-compatible version (actually there is only GlassFish 5). However, the tasks covered here shouldn't change in a future version, as they are not attached to the Java EE specs. To download it, just visit http://wildfly.org/downloads/.

This recipe in based on version 11.0.0.Final (Java EE7 Full and Web Distribution).

Wherever possible, we will focus on doing the tasks using the configuration files.
