Oops, the documentation led me to believe that I need to configure 
*both* ! In http://jboss.org/mod_cluster/java/config.html, the 
configuration of ModClusterListener is under "Common Configuration", so 
I thought this needs to be added no matter what...

Voila, I removed ModClusterListener from server.xml, and I can now see 
the domains in mod-cluster-manager, great !

thanks for you help !
