21.4.1. About Common Object Request Broker Architecture (CORBA)
Common Object Request Broker Architecture (CORBA) is a standard that enables applications and services to work together even when they are written in multiple, otherwise-incompatible, languages or hosted on separate platforms. CORBA requests are brokered by a server-side component called an Object Request Broker (ORB). JBoss EAP 6 provides an ORB instance, by means of the JacORB component.
The ORB is used internally for Java Transaction Service (JTS) transactions, and is also available for use by your own applications.
