I am just starting a new web application (as a learning project). I have some freedom to choose what framework I use, but I must use JavaEE, it must be MVC, and it must run on Tomcat 6.0.24. I've decided to go with JSF 2, using the MyFaces implementation (the choice of MyFaces was arbitrary...I just need to get started with something to learn, but I wanted it to be something used in practice for real-world apps). The latest release is 2.1.11, and I figured I'd go with that. However, will I run into any problems trying to run an app built with MyFaces 2.1.11 on Tomcat 6.0.24? I'm new to Java web development and JSF, so I wasn't sure if there'd be any issues, but I don't want to get down this path (especially starting from scratch with whichever framework I use) and realize that my app won't work with Tomcat 6.0.24. Thanks.
Ok, as I've done some more reading and practicing over the past week, things have become clearer and the feeling of being overwhelmed by buzzwords has subsided a bit. In retrospect, getting JSF 2 and JSTL in place were pretty easy, and I now have what I think is a fully functional development environment.
Confirming the supported Servlet/JSF versions in Tomcat was a cinch. Using Eclipse Indigo, JavaEE 6, Apache MyFaces 2.1.11, and JSTL 1.2.1, my (very simple) test apps worked on Tomcat 6.0.24.
This was a very specific question, so I'm not sure whether it will be of use for anyone else, but I figured I'd give an answer just for completeness. Thanks to BalusC for his input on this question and for his many other contributions on SO!
