JBoss HA relies on JGroups for communication. It is very easy to work with, but if it doesn't it gets little difficult to troubleshoot. This is what i realized last week when i tried to set it up on two machines. Here are the steps you can follow if you are stuck:
1. Check whether multicast works - http://www.jboss.org/file-access/default/members/jbossas/freezone/docs/Clustering_Guide/4/html-single/index.html#id3016498
Want to read some theory on multicast - http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/Multicast-HOWTO.html
2. Check if JGroups is able to establish communication channels - http://myt.ag/URLWeb.aspx?email=steve%40fooworks.com&url=http%3a%2f%2fwiki.jboss.org%2fwiki%2fWiki.jsp%3fpage%3dTestingJBoss&sn=
3. Enable logging in JBoss to see more info - http://www.jboss.org/community/docs/DOC-9164
4. Make sure that you are not booting JBoss with -b 0.0.0.0. Give IP address of machine instead of 0.0.0.0
