JBoss 4.2 TCP Clustering problem
I am upgrading JBoss from 4.0.5 to 4.2.3 and unable to set up clustering on the new version. I have spent quite a bit of time reading clustering FAQ and Wiki\JbossHA. I was unable to find a good TCP clustering example for 4.2.x. I have JBoss installed on 2 windows boxes and starting it with -c all. I cannot get the JGroups layer to work - nodes don't discover each other: the log on each box always show:
2008-11-05 15:40:07,263 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Number of cluster members: 1
2008-11-05 15:40:07,263 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Other members: 0
2008-11-05 15:40:07,263 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] Fetching state (will wait for 30000 milliseconds):
2008-11-05 15:40:14,326 INFO [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] State could not be retrieved (we are the first member in group)
I am using TCP transport and my config in cluster-service.xml is like this:
<TCP bind_addr="box1" start_port="7800" loopback="true"
tcp_nodelay="true"
recv_buf_size="20000000"
send_buf_size="640000"

<pbcast.GMS print_local_addr="true" join_timeout="3000"

Please help!
A working config example for JBoss 4.2 would help a lot.
Thank you,
