How to find out which implementation is running

Hi

When I want to write a component that must run under more than
JSF-implementation,
I often should know (runtime not development time) which implementation
is running, in
order to use the correct base-classes.

Has somebody devised a clever method to find out which JSF-runtime is
active?
Or should we add something to enable this?

regards
Alexander

Facelets has figured out this:

Here's the class to imitate.

It's basically checking for the existance of

Application.class.getExpressionFactory()

Good question.

If you devise something like this, there should also be a way to check
for the spec version of the jsf implementation running.
