Could not create a connection for cluster node ClusterNode in JBoss EAP 7 / 6

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 7.x
  • 6.x

Issue

• We are able to invoke a single node, but when we configure our ejb-client to invoke a cluster, it fails to connect to the cluster nodes with this message:

INFO: Could not create a connection for cluster node ClusterNode{clusterName='ejb', nodeName='node1:server', clientMappings=[ClientMapping{sourceNetworkAddress=/0:0:0:0:0:0:0:0, sourceNetworkMaskBits=0, destinationAddress='192.168.1.100', destinationPort=12345}], resolvedDestination=[Destination address=192.168.1.100, destination port=12345]} in cluster ejb

		return new PropertiesBasedEJBClientConfiguration(prop);

Resolution

In JBoss EAP 7.0 / 6.4 , the ejb-client needs to also specify the cluster username and password such as:

p.put("remote.cluster.ejb.username", "user");
p.put("remote.cluster.ejb.password", "password");

In JBoss EAP 7.1+ it included a feature that simplifies the configuration and would not need the cluster configuration specified.
