This page provides a starting point for finding information about Java Transaction API (JTA) support. Applications running on the server can use transactions to coordinate multiple updates to resources as one unit of work, such that all or none of the updates are made permanent.
The product provides advanced transactional capabilities to help application developers avoid custom coding. It provides support for the many challenges related to integrating existing software assets with a Java EE environment.
You can configure application servers so that transaction messages are sent and received between application servers at different versions of WebSphere® Application Server. Depending on the version of the application server, you can set system properties, or use the transaction coordination authorization setting.
