Managing Information Access to an Enterprise Information System Using J2EE and Services Oriented Architecture

Preface

This IBM Redbook focuses on issues associated with the integration of an

existing enterprise information system (EIS) into a new Java 2 Platform,

Enterprise Edition (J2EE), and other service-oriented applications. The book

specifically discusses quality of service issues that are associated with the

integration of geographically remote EIS. It describes how to use Web services,

Java Message Service (JMS), and J2EE Connector Architecture (JCA)

technologies in combination to enable access to existing transactions while

addressing transport difficulties due to variable network conditions. It also

addresses security context and transaction context propagation issues.

The audience for this book is architects and developers who are implementing

new J2EE and service oriented architecture (SOA) solutions that need to be

integrated with existing EIS systems.
