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@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/
