Programming with the Java Transaction API
With a general understanding of transactions under your belt, it’s time to look more at how transactions are supported by the J2EE platform. To provide the transactional capabilities needed by a J2EE application, an EJB container is required to support the high-level interface defined by the Java Transaction API (JTA) for transaction demarcation. Don’t worry if you don’t know what that means just yet. The best way to understand JTA and its role in EJB is to look at how it relates to several key specifications on transaction processing. This background will help you see the big picture into which JTA fits and get a quick introduction to the terminology involved in describing transactional systems.
