Unfortunately in order to get JMX to bind to dedicated address (and not just 0.0.0.0) you have to jump through a few hoops. In order to save you some time - here is how you do it. Create your own RMISocketFactory that only creates server sockets on the specified address

public class RMIServerSocketFactoryImpl implements RMIServerSocketFactory {

    private final InetAddress localAddress;

    public RMIServerSocketFactoryImpl( final InetAddress pAddress ) {
        localAddress = pAddress;
    }

    public ServerSocket createServerSocket(final int pPort) throws IOException  {
        return ServerSocketFactory.getDefault()
            .createServerSocket(pPort, 0, localAddress);
    }

    public boolean equals(Object obj) {
        if (obj == null) {
            return false;
        }
        if (obj == this) {
            return true;
        }

        return obj.getClass().equals(getClass());
    }

    public int hashCode() {
        return RMIServerSocketFactoryImpl.class.hashCode();
    }
}

Then create the naming service with that factory and create the RMI server using that naming service.

RMIServerSocketFactory serverFactory = new RMIServerSocketFactoryImpl(InetAddress.getByName(address));

LocateRegistry.createRegistry(namingPort, null, serverFactory);

StringBuffer url = new StringBuffer();
url.append("service:jmx:");
url.append("rmi://").append(address).append(':').append(protocolPort).append("/jndi/");
url.append("rmi://").append(address).append(':').append(namingPort).append("/connector");

Map env = new HashMap();
env.put(RMIConnectorServer.RMI_SERVER_SOCKET_FACTORY_ATTRIBUTE, serverFactory);

rmiServer = new RMIConnectorServer(
   new JMXServiceURL(url.toString()),
   env,
   ManagementFactory.getPlatformMBeanServer()
   );

rmiServer.start();

Why do some so simple things need to be so overly complicated?
