I'm not sure what you mean. In AS 6 the most relevant things are the 
mbean interfaces exposed by the JBoss Web StandardManager class 
(non-clustered) versus the AS's JBossCacheManager class (clustered). 
There the latter's mbean interface is a superset of the former's. That's 
to account for some configuration options that jboss-web.xml exposes for 
clustered webapps (IMHO valid to expose) and the fact that a distributed 
session cache inherently has a different set of capabilities from a 
non-distributed one -- primarily that it can store (and thus use 
resources for) backup copies of sessions that are being handled on other 
servers in the cluster. If a tool doesn't want to expose that extra 
information it doesn't have to.
