Do the other application servers ship with their own JSF implementation?
Glassfish ships with the JSF 1.2 reference implementation. Supporting JSF 1.2 is required for all JavaEE 5 platforms, so this is going to be a universal issue for that generation of servers.
If so, do they offer any other way of substituting another JSF
implementation into one's application?
We (Sun) are looking at that issue for Glassfish at the moment.
