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 the use of service-oriented architecture and the

enterprise service bus to build solutions that help organizations achieve rapid,

flexible integration of IT systems.

It includes the Self-Service::Directly Integrated Single Channel pattern for

implementing point-to-point connections with back-end applications, the

Self-Service::Router pattern for implementing intelligent routing among multiple

back-end applications, and the Self-Service::Decomposition pattern for

decomposing a request into multiple requests and recomposing the results into a

single response.

This IBM Redbook teaches you by example how to design and build sample

solutions using WebSphere® Application Server V6 with Web services, J2EE™

Connectors and IBM CICS®, and JMS using the WebSphere Application Server

default messaging provider. WebSphere Application Server service integration

technology is used to implement enterprise service bus functionality.
