Book description

This IBM Redbook will help you plan and execute the migration of J2EE 1.3 applications developed for BEA WebLogic Server 8.1, JBoss 3.2.7 and Apache Tomcat 5.5.9, so that they will run on WebSphere Application Server V6.

This redbook provides detailed information to help you plan migrations, best practices for developing portable applications as well as migration working examples for each of the platforms from which we migrated.

It is not our intention to provide a feature-by-feature comparison of BEA WebLogic Server 8.1, JBoss 3.2.7 and Apache Tomcat 5.5.9 versus WebSphere Application Server V6, nor to argue the relative merits of the products, but to produce practical technical advice for developers who have to migrate applications from these vendors to WebSphere Application Server V6.
