Transaction Management

Comprehensive transaction support is among the most compelling reasons to use the Infra Framework. The TODAY Framework provides a consistent abstraction for transaction management that delivers the following benefits:

A consistent programming model across different transaction APIs, such as Java Transaction API (JTA), JDBC, Hibernate, and the Java Persistence API (JPA).
Support for declarative transaction management.
A simpler API for programmatic transaction management than complex transaction APIs, such as JTA.
Excellent integration with Infra data access abstractions.

The following sections describe the TODAY Framework’s transaction features and technologies:

Advantages of the TODAY Framework’s transaction support model describes why you would use the TODAY Framework’s transaction abstraction instead of EJB Container-Managed Transactions (CMT) or choosing to drive transactions through a proprietary API.
Understanding the TODAY Framework transaction abstraction outlines the core classes and describes how to configure and obtain DataSource instances from a variety of sources.
Synchronizing resources with transactions describes how the application code ensures that resources are created, reused, and cleaned up properly.
Declarative transaction management describes support for declarative transaction management.
Programmatic transaction management covers support for programmatic (that is, explicitly coded) transaction management.
Transaction bound event describes how you could use application events within a transaction.

The chapter also includes discussions of best practices, application server integration, and solutions to common problems.
