J2EE includes support for distributed transactions through two specifications, Java Transaction API (JTA) and Java Transaction Service (JTS). JTA is a high level, implementation independent, protocol independent API that allows applications to access transactions. JTS specifies the implementation of a Transaction Manager which supports JTA and implements the Java mapping of the OMG Object Transaction Service (OTS) 1.1 specification using the IIOP protocol. The JTA API allows you to demarcate transactions in a manner that is independent of the transaction manager service or JTS.

While JTA provides an API for demarcating transactions in Java-based application logic, XAML provides an agreed upon protocol or a coordinated process of interaction among transactionally-aware web services over a defined transport. Given this, a web service internally implementing JTA could expose these transactional capabilities using XAML.
