It's about ties to specific deployment units, deployment services, runtime services - and how much of your code is affected there. Of course this requires some careful architectural design in the application as well, but the nature of the fundamental component and configuration model already makes a big difference here. J2EE's track record isn't great in that respect, at least for EAR files. The use of Spring within a WAR file constitutes a significantly better basis here. This is what we're hearing from our users who attempted such migrations between different application servers, or even simply between different generations of the same application server. People also appreciate that Spring's full-fledged Java 5 component model is available on J2EE 1.4 servers such as WebLogic 9.2 and WebSphere 6.1...
