Java Transaction API - JTA - Distributed Transaction İçindir

Giriş

Açıklaması şöyle

The Java Transaction API (JTA) is one of the APIs defined in the Java Enterprise Edition (Java EE) platform, specifically providing a framework for handling distributed transactions in a consistent and reliable manner.

Açıklaması şöyle

The Java Transaction API consists of three key elements:

UserTransaction interface: This provides the application with the ability to control transaction boundaries programmatically.

TransactionManager interface: It offers more advanced features, like suspending, resuming transactions, and is typically used by the container rather than by the application.

XAResource interface: This is the bridge between the resource manager (like a database) and the transaction manager. It includes methods for associating a resource with a transaction and for transaction completion.
