When I startup my Glassfish 2.1 server, it seems to startup without problems, but when I try to access its Admin console I get the error:
The requested resource (Servlet FacesServlet is not available) is not available.
On its console and server.log, this is what I can see:
[#|2013-05-09T14:59:36.647+0200|INFO|sun-appserver2.1|javax.enterprise.system.core|_ThreadID=10;_ThreadName=main;|Application server startup complete.|#]

The last 2 entries are logged when I access the Admin console for the first time.
Why is glassfish marking FacesServlet as unavailable?
I had Richfaces jars in my glassfish_home/lib/ext directory that were somehow causing this problem.
If I remove them I'm able to use the Admin console again.
