Microsoft ASP.NET MVC - Why Java web developers should reconsider action frameworks?

Microsoft's ASP.NET MVC is a paradigm shift in web development from its pioneering component based development offered with WebForms to action based web framework. This was a natural evolution due to the pains in the component based web development. While the Java community started out with the action based frameworks, the shift of the community seems to be on a higher side for the component based web development led by JavaServer Faces (JSF) in the recent years. The shift of Microsoft towards action frameworks should make the Java web developer's heads again turn towards action frameworks and reconsider their choice towards the paradigm for web development. Perhaps a thinking about polyglot web development is needed, rather than abandoning action frameworks.
