Chapter 4. Transactions on JBoss

IN THIS CHAPTER

• Transaction and JTA Overview

• JBoss Transaction Internals

This chapter discusses transaction management in JBoss and the JBossTX architecture. The JBossTX architecture allows for any Java Transaction API (JTA) transaction manager implementation to be used. JBossTX includes a fast in-VM implementation of a JTA compatible transaction manager that is used as the default transaction manager. We will first provide an overview of the key transaction concepts and notions in the JTA to provide sufficient background for the JBossTX architecture discussion. We will then discuss the interfaces that make up the JBossTX architecture and conclude with a discussion of the MBeans available for integration of alternate transaction managers.
