Chapter 11. Subsystem Configuration

11.1. Subsystem Configuration Overview


JBoss EAP 6 uses a simplified configuration, with one configuration file per domain or per standalone server. In domain mode, a separate file exists for each host controller as well. Changes to the configuration persist automatically, so XML configuration file should not be edited manually. The configuration is scanned and overwritten automatically by the Management API. The command-line based Management CLI and web-based Management Console allow you to configure each aspect of JBoss EAP 6.

JBoss EAP 6 is built on the concept of modular class loading. Each API or service provided by the Platform is implemented as a module, which is loaded and unloaded on demand. Most modules include a configurable element called a subsystem. Subsystem configuration information is stored in the unified configuration file EAP_HOME/domain/configuration/domain.xml for a managed domain or EAP_HOME/standalone/configuration/standalone.xml for a standalone server. Many of the subsystems include configuration details that were configured via deployment descriptors in previous versions of JBoss EAP.
Subsystem Configuration Schemas

Each subsystem's configuration is defined in an XML schema. The configuration schemas are located in the EAP_HOME/docs/schema/ directory of your installation.
