11.2.6. About Java Transaction Service (JTS)

Java Transaction Service (JTS) is a is a mapping of the OTS to Java. Java applications use the JTA API to manage transactions. JTA then interacts with a JTS transaction implementation when Transaction manager is switched to JTS mode. To use special JTS capabilities, for example, nested transaction, you need to manually use the JTS API.
JTS works over IIOP protocol. Transaction managers that use JTS, communicate with each other using a process called an Object Request Broker (ORB), using a communication standard called Common Object Request Broker Architecture (CORBA).
Using JTA API from an application standpoint, a JTS transaction behaves in the same way as a JTA transaction.

Note

The implementation of JTS included in JBoss EAP 6 supports distributed JTS transactions across multiple JBoss EAP 6 servers. The difference between distributed JTS transactions and fully-compliant JTS transactions is the interoperability with external third-party ORBs. This feature is unsupported with JBoss EAP 6.
