I have a Java client that successfully connects to ActiveMQ Artemis JMX when both are running on the same machine. The client uses the following code:

public static void main(String[] args) throws IOException, MalformedObjectNameException, ReflectionException, AttributeNotFoundException, InstanceNotFoundException, MBeanException 
{    
    private static final String JMX_URL = "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi";
    System.out.println("Hello, Artemis!");
    HashMap env = new HashMap();
    String[] creds = {"artemis", "artemis"};
    env.put(JMXConnector.CREDENTIALS, creds);
    JMXConnector connector = JMXConnectorFactory.connect(new JMXServiceURL(JMX_URL), env);  
    MBeanServerConnection mBeanServer = connector.getMBeanServerConnection();    
    System.out.println("Connected to the server");
}

ISSUE: When I move ActiveMQ Artemis into a Docker container with necessary ports exposed, I get the following error:

java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment;

What we tried:

• Exposed JMX Ports in Docker
• Added Java Argument in artemis.profile (-Djava.rmi.server.hostname=localhost)
• Enabled Connector Element in management.xml ( <connector connector-port="1099" connector-host="localhost"/> ). Also tried replacing localhost with 0.0.0.0, but the issue persists.
• After building and running the Docker image locally, I confirmed that RMI registry is listening on port 1099, but I still cannot connect.

• java
• docker
• rmi
• jmx
• activemq-artemis

• Any feedback here? – Justin Bertram Commented Feb 10 at 3:12

I recommend you try setting the rmi-registry-port attribute on the connector, e.g.:

<connector connector-port="1099" rmi-registry-port="1100" connector-host="localhost"/>

Then ensure that port is exposed by Docker.
