Book description

This IBM® Redbooks® publication helps you plan and execute the migration of J2EE applications that are developed for Oracle WebLogic Server, Oracle Application Server, JBoss, and Apache Tomcat, so that they run on IBM WebSphere® Application Server V8.5. In addition, this book covers migration from earlier versions of WebSphere Application Server to WebSphere Application Server V8.5.

This book provides detailed information to plan migrations, suggested approaches for developing portable applications, and migrating working examples for each of the platforms from which we migrated in our examples. The primary tool that is used in the migration scenarios that are covered in this book is the IBM WebSphere Application Server Migration Toolkit V3.5.

It is not our intention to provide a feature-by-feature comparison of these application servers versus WebSphere Application Server, but to produce practical technical advice for developers who must migrate applications from these vendors to WebSphere Application Server V8.5.

This publication is an update of WebSphere Application Server V7: Competitive Migration Guide, SG24-7870.

The book is intended as a migration guide for IT specialists who are working on migrating applications that are written for other application servers or earlier versions of WebSphere Application Server to WebSphere Application Server V8.5.

Please note that the additional material referenced in the text is not available from IBM.
