Transaction support in JBoss Enterprise Web Platform is provided by JBoss Transaction Service, a mature, modular, standards-based, highly configurable transaction manager. By default the server runs with the local-only JTA module of JBossTS installed. This module provides an implementation of the standard JTA API for use by other internal components, such as the EJB container, as well as direct use by application code. It is suitable for coordinating ACID transactions that involve one or more XA Resource managers, such as databases or message queues.
