I've started playing with clustering in WildFly 8 and been able to create a simple sample that shows HTTP session failover. The sample is at: https://github.com/arun-gupta/wildfly-samples/tree/master/clustering/http I'll be sharing a blog post on this soon. In the mean while here is some initial feedback: 1). Starting domain.sh automatically starts two WildFly instances on 8080 and 8230. Clicking on "Administration Console" shows the message " if you are running a domain the http interface can not be automatically detected so check the host.xml configuration and connect directly.". I think this message can be improved by saying what needs to be done in order to access the console. 2). If a WildFly instance needs to run on multiple hosts then it seems like it needs to be manually copied over to each machine. Is there a mechanism where a zip bundle can be sftp/ssh copied over to the remote machine ? This would simplify setting up a cluster. 3). Changed server-two auto-start="false" and server-three auto-start="true". Running domain.sh gives the following error: [Server:server-three] 15:17:03,924 INFO [org.jboss.messaging] (MSC service thread 1-12) JBAS011615: Registered HTTP upgrade for hornetq-remoting protocol handled by http-acceptor-throughput acceptor [Server:server-three] 15:17:03,978 ERROR [org.hornetq.core.server] (Thread-0 (HornetQ-scheduled-threads-45430818)) HQ224033: Failed to broadcast connector configs: java.io.IOException: Can't assign requested address [Server:server-three] at java.net.PlainDatagramSocketImpl.send(Native Method) [rt.jar:1.7.0_45] [Server:server-three] at java.net.DatagramSocket.send(DatagramSocket.java:676) [rt.jar:1.7.0_45] [Server:server-three] at org.hornetq.api.core.UDPBroadcastGroupConfiguration$UDPBroadcastEndpoint.broadcast(UDPBroadcastGroupConfiguration.java:135) [hornetq-core-client-2.4.1.Final.jar:] [Server:server-three] at org.hornetq.core.server.cluster.impl.BroadcastGroupImpl.broadcastConnectors(BroadcastGroupImpl.java:215) [hornetq-server-2.4.1.Final.jar:] [Server:server-three] at org.hornetq.core.server.cluster.impl.BroadcastGroupImpl.run(BroadcastGroupImpl.java:227) [hornetq-server-2.4.1.Final.jar:] [Server:server-three] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) [rt.jar:1.7.0_45] Is there something else that needs to be configured ?
