I've got the same issue with Equinox + PAX Web + Jetty + JSF 2.0.2. Looks more like a JSF issue in OSGi environments (Since GF3 is also OSGi based) then a Glassfish issue ?
[edit]
Scrapped previous fix, is not what fixed it. I copied all the settings from faces-config.xml of the IceFaces core library (in META-INF) to my own faces-config.xml.
If you are trying to create a pure ICEfaces-2.0 project, then the <ice: components are still being developed at this time (hence the Alpha state). If you review the bundled sample applications, you can see that the "h" and "f" tags are used for pure ICEfaces-2.0 development at this point in time.
If you want to use <ice: components, then you have to include the compat jars. Just something to check and make sure that it isn't causing your current problem.
