The JavaTM 2 Platform, Enterprise Edition (J2EETM) connector architecture (JCA) is the key component for enterprise application integration (EAI) in the JavaTM technology platform. In addition to facilitating enterprise application integration, the connector architecture helps integrate existing enterprise applications and information systems with Web services and applications. Two chapters from a book on this topic are available online from the Java Developer ConnectionSM (JDC) Program. The book "J2EE Connector Architecture and Enterprise Application" by Rahul Sharma, Beth Stearns and Tony Ng is written for J2EE application developers and addresses the problems faced by Web-based enterprise environments for integrating existing enterprise systems and applications.

Rahul Sharma is a senior staff engineer and lead architect of the J2EE connector architecture with Sun. Beth Stearns is the principal partner of ComputerEase Publishing, a computer consulting firm. Tony Ng is a staff engineer with Sun and is currently the project lead of the JavaTM 2 Software Development Kit and Reference Implementation. He has designed and implemented a number of Java technologies, including the J2EE Connector Architecture, the Java Transaction Service and the J2EE Blueprints.

Chapter 1, "Enterprise Application Integration," describes the state of enterprise application integration today and shows its evolution.

Chapter 10, "Building a Resource Adapter," describes the steps involved in building a system-level software driver that provides the connection to the vendor's EIS.
