Although Spring and EJB isolate us from most of the complexities involving transaction management, there are still a number of things we need to be aware of when dealing with transactions in Enterprise Java Applications. Too often transaction management is an afterthought in the design and development process, which leads to applications that have problems with data integrity, data consistency, and overall stability and reliability. In this session we will explore the three transaction models that both Spring and EJB support (Local, Programmatic, and Declarative), and discuss the advantages, disadvantages, and pitfalls within each of these models, when it makes sense to use each transaction model, and under what situations these models are appropriate and inappropriate. We will spend most of our time on the Declarative Transaction Model. Within this model we will explore some common pitfalls and look at the best practices within this model. Through coding examples in both EJB and Spring using real-world scenarios, you will learn how to properly handle exceptions, how to correctly use transaction attributes, and how the isolation level can affect transaction and application behavior. This session is the first part of a 3 hour transaction management session.
