Jboss Cluster with Window NLB
Hi,
I've setup 2 machine to run both MS NLB for load balancing and Jboss AS 4.2.2GA for Clustering.
1st machine's IP address is 192.168.0.3
2nd machine's IP address is 192.168.0.7
The virtual IP exposed by the NLB for both machines is 192.168.0.225
I've start the Jboss Server to run under all mode which as below:-
run -b 0.0.0.0 -c all
I've change the ClusterConfig for both all\deploy\cluster-service.xml and all\deploy\jboss-web-cluster.sar\META-INF\jboss-service.xml file to run under TCP setting as below :-

Everything seems ok when I startup both server. And I can see that both server was detect and join with each other in the same cluster.
But I get the below error message keep showing in both server console.
Error keep showing in machine 192.168.0.7

It seems like the State was not transfer among the server.
What I've doing wrong with my configuration? How to resolve the error message? your help is much appreciated! Thank You!
