mod_cluster 1.2 + JBoss AS 7.1.3, mod_cluster_manager sees no nodes

[prhodes_osi]

Hi all, I'm trying to test  a simple two node cluster using mod_cluster 1.2 and JBoss AS 7.1.3.  I have Apache httpd and one JBoss instance running on server "betty1" with IP 192.168.41.180 and another JBoss node on server "betty2" with IP 192.168.41.181.   JBoss is running in domain mode and I have deployed a trivial cluster-demo app with a <distributable /> tag.  So far, I'm unable to have mod_cluster_manager report that it sees any of the nodes in the cluster.   I already gave up on using server advertise, which strikes me as fairly brittle from other forum posts and what-not, so I decided to fall back to a manually specified proxy-list.  Unfortunately, even that doesn't work.   I'm hoping this is just some missed config option or something on my part, so I'll share my config her and hope someone can help.

httpd.conf:

{code:xml}

Thoughts or suggestions?

at a first look the configuration looks OK.

Check that the nodes could connect to httpd (like using curl -v http://192.168.41.180:6666/mod_cluster_manager on each node) looks to the response.

No response you have to open the port 6666 in the firewall.

Error then check in error_log or access_log to find what happens.
