Chapter 8. JDO and the J2EE Connector Architecture

“Creativity is the power to connect the seemingly unconnected.”

—William Plomer

This chapter explains how JDO can be used in conjunction the Java 2 Platform, Enterprise Edition (J2EE) via the J2EE Connector Architecture. This allows a JDO implementation to collaborate with a J2EE-compliant Application Server on security, transaction, and connection management. This chapter assumes familiarity with the J2EE concepts and development.

This chapter covers the following topics:

• A brief introduction to the J2EE Connector Architecture.

• How the J2EE Connector Architecture and JDO fit together.

• Using JDO and the J2EE Connector Architecture to build J2EE applications.

• Using JDO without the J2EE Connector Architecture to build J2EE applications.

Chapter 9 provides greater detail on actually using JDO to build J2EE applications. This chapter aims to provide an introduction by explaining how JDO and J2EE can interoperate. In this context, a J2EE application refers to either a Servlet or an Enterprise JavaBean.
