[jboss-user] [JBoss Cache Users] - JGroups multicast works, JBC cluster doesn't form with same

[chtimi2]

I'm trying JBC clustering, but so far the cluster never goes past 0 nodes.
Yes not 1, but 0 nodes!
cache = org.jboss.cache.pojo.impl.PojoCacheImpl cache=org.jboss.cache.DataContainerImpl [0 nodes, 0 locks] delegate=org.jboss.cache.pojo.impl.PojoCacheDelegate at 5bd978 types=0

I have tried some tests to see where it might come from:

1/ The JGroups drawing test at http://www.jgroups.org/tutorial/html/ch01.html works perfectly, so at least multicast works. 

2/ The JBoss cache tutorial test with the 2 little clients works  

3/ My two nodes using the default JGroups conf (used by 1/)

  | <clustering mode="replication">
  | 	    <jgroupsConfig configFile="udp.xml" />
  |       	<sync />
  | </clustering>
  | 

-->0 nodes on both JVMs

4/ My two nodes using the sample conf total-replication.xml (used by 2/),
and supplying the same runtime arguments as 2/
