5.6. Additional Services

The non-core, hot-deployable services are added to the deploy directory (refer to Chapter 6, Hot Deployment of Services). They can be either XML descriptor files, *-service.xml, *-jboss-beans.xml, MC .beans archive, or JBoss Service Archive (SAR) files. SARs contains an META-INF/jboss-service.xml descriptor and additional resources the service requires (for example, classes, library JAR files or other archives), all packaged up into a single archive. Similarly, a .beans archive contains a META-INF/jboss-beans.xml and additional resources.

Detailed information on all these services can be found in the Administration and Configuration Guide, which also provides comprehensive information on server internals and the implementation of services, such as JTA and the J2EE Connector Architecture (JCA).
