JMS client to ActiveMQ at server on Red Hat JBoss EAP 7.3 in Java

I am writing a Java client to connect to my JBoss EAP 7.3 server running ActiveMQ, and I am getting various connection responses as I alter the parameters. Please help me correct the parameters/code. I get:

09:46:57.227 [main] INFO org.xnio.nio - XNIO NIO Implementation Version 3.4.6.Final

This is the Java client code in a try catch block attempting to connect:

            Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
            env.put(Context.PROVIDER_URL, "http-remoting://127.0.0.1:8080");  
            env.put(Context.SECURITY_PRINCIPAL,adminUser);
            env.put(Context.SECURITY_CREDENTIALS, adminPassword);
            Context  namingContext = new InitialContext(env);

            String CONNECTION_FACTORY = "java:jboss/exported/jms/RemoteConnectionFactory"; 
                        ConnectionFactory connectionFactory = (ConnectionFactory) namingContext.lookup(CONNECTION_FACTORY);
            System.out.println("Got ConnectionFactory");

            Destination destination = (Destination) namingContext.lookup(QUEUE);  // Sure QUEUE is correct
            System.out.println("Got JMS Endpoint " + QUEUE);

            JMSContext context = connectionFactory.createContext(adminUser, adminPassword);
            context.createProducer().send(destination, xmlContent);
            System.out.println("Got JMS destination");

And these are my JNDI tree values in the EAP management console for java:jboss/exported >> JMS >>

Answer

It looks to me like you’re using the wrong InitialContextFactory implementation. Try using org.wildfly.naming.client.WildFlyInitialContextFactory instead of org.jboss.naming.remote.client.InitialContextFactory.

You can find a full JMS client example for JBoss EAP 7.3 here.
