This article demonstrates a innovative way to use the OSGi framework within a Web application. I belive the force of OSGi to provide a clean plug-in approach to application development could lead to a whole new approach to mantainence and development of J2EE apps (I think there is also a .Net implementation of OSGi so that could go for ASP.NET as well). Potentially you could dynamicly extend/change your web-app on the fly. Something that it’s very hard to do today and it would lead to easy extendibility of your application having some clean point cuts on how do they fit together.
