Wildfly Clustering using JBoss

Question

I'm trying to set up a Wildfly 11 cluster but I'm not able to make it work. Basically, I have 2 instances of Wildfly with one instance having port-offset=2 running on my local machine. Here are the publisher and MDB:

@JMSDestinationDefinitions(value = { @JMSDestinationDefinition(name = "java:/topic/CLUSTEREVENTTOPIC", interfaceName = "javax.jms.Topic", destinationName = "ClusterEventTopic") })
@Stateless
public class ClusterEventPublisher implements Serializable {

MDB

@MessageDriven(name = "ClusterEventMonitor", activationConfig = { @ActivationConfigProperty(propertyName = "destinationLookup", propertyValue = "topic/CLUSTEREVENTTOPIC"),
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
        @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge") })
public class ClusterEventMonitor implements MessageListener {

Note that I'm able to see this topic created on Wildfly, but when I publish a message on the topic. It's only read by the node that sends the message.

For example: node1 sends an eventDto as the message, node1 will receive the message but not node2.

Note that I'm using standalone-full-ha.xml configuration. I just added the following line in ActiveMQ module:

<cluster password="${jboss.messaging.cluster.password:opencell}"/>

Full config is downloadable from, note that the second instance has exactly the same configuration with the only difference being the port-offset value:

I'm on debug mode and sure that the message doesn't reach node2. Any idea?

Answer 1

I'm now able to receive the message send from node1 via JMS in node2. However, I really did not do anything. I compared my configuration files and they are almost the same with my first set of nodes that don't work. What I did was just download a new Wildfly 11 zipped, do the necessary database configuration and it worked. For those asking, here's part of my standalone-full-ha.xml config:

As for infinispan cache:

<cache-container name="projectx">
    <transport lock-timeout="60000"/>
    <replicated-cache name="projectx-cache" mode="SYNC">
        <transaction mode="NON_XA"/>

    </replicated-cache>

And ActiveMQ

<subsystem xmlns="urn:jboss:domain:messaging-activemq:2.0">
    <server name="default">
        <cluster password="${jboss.messaging.cluster.password:secret}"/>

Make sure that you bind your server to your IP address or 0.0.0.0 for testing.
