Struts is by far the most common web framework, but it is by no means the only option. Java Server Faces has made a splash lately, but there are a number of open source alternatives, including Spring MVC, WebWork, Tapestry, and Cocoon.
I’ve found two interesting presentations that survey these available web frameworks, taking a look at what kind of code and content you need to write for each, specific strengths or weaknesses, and how to select the best web framework for your unique application requirements.

- Comparing Web Frameworks by Brian McCallister, Greg Hinkle, Erin Mulder
The second one takes even a closer look at how do these web frameworks work.
