Core Java Data Objects

"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.
