Preface

---

The Patterns for e-business are a group of proven, reusable assets that can be used to increase the speed of developing and deploying Web applications. This IBM® Redbook focuses on point-to-point application integration using the Process-focused Application Integration::Direct Connection application pattern for intra-enterprise, and the Extended Enterprise::Exposed Direct Connection application pattern for inter-enterprise.

Part 1 guides you through the process of selecting an Application and Runtime pattern. Next, the platform-specific Product mappings are identified based upon the selected Runtime pattern.

Part 2 presents guidelines on applying the Patterns approach to a sample business scenario and on selecting application integration technologies.

Part 3 provides detailed design, development, and runtime guidelines for intra-enterprise integration solutions. It teaches you by example using IBM WebSphere Application Server V5.0 with Web services, J2EE Connectors, and JMS.

Part 4 provides detailed design, development, and runtime guidelines for inter-enterprise integration solutions. It teaches you by example using IBM WebSphere Application Server V5.0 with Web services.
