Compare JSF implementations [closed]

Question

I would be glad to get references to resources and people's experience on comparison of known JSF implementations: MyFaces and IceFaces in terms of component's richness, ease to develop, popularity, stability, community support, etc.

Update: as it was pointed out the initial question is not accurate enough. There are few JSF implementations (Apache MyFaces, Sun reference implementation) and some JSF component libraries (IceFaces, RichFaces, Woodstock, etc.). But anyhow my question is about both core JSF and JSF component libraries implementations.

Answer 1

Be careful!

JSF is a specification. Thus, you must use an implementation, such as the one provided by Sun, or the one provided by Apache (MyFaces).

IceFaces is not an implementation, but a component library. Other libraries exist, such as RichFaces, MyFaces Tomahawk, and so on.

You can have a look here for the differences between components libraries.
