Barebones JSF2 Eclipse project

Quick view on minimal libraries required to get a JSF2 project running in Eclipse (should work everywhere else):

• com.springsource.javax.servlet.jsp-2.1.0.jar ==> Obtained from Spring framework dependencies package
• com.springsource.javax.servlet.jsp.jstl-1.1.2.jar ==> Obtained from Spring framework dependencies package
• javax.faces.jar ==> Obtained from http://javaserverfaces.java.net/.  Downloaded Mojarra 2.1 release.  Available in Spring framework dep package, but it's an older version (1.2).
• jstl-impl-1.2.jar  ==> Obtained from http://jstl.java.net/.  Available in Spring framework dep package, but it's an older version (1.1.2).

You can start developing a JSF2 app with just these 4 files.  Have tried the following:

• Facelets (xmlns:ui="http://java.sun.com/jsf/facelets")
• HTML elements (xmlns:h="http://java.sun.com/jsf/html")
• Core elements (xmlns:f="http://java.sun.com/jsf/core")

I used Apache Tomcat 7.  But I'm sure this will work with other app server/servlet containers as well.
