Is it possible to enable remote jmx monitoring programmatically?

I need to programmatically start a new java process and dynamically set the JMX port. So instead of doing this

-Djava.rmi.server.hostname=127.0.0.1 -Dcom.sun.management.jmxremote.port=9995 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

I would like to do the following

System.setProperty("java.rmi.server.hostname", "127.0.0.1" );
System.setProperty("com.sun.management.jmxremote", "true" );
System.setProperty("com.sun.management.jmxremote.authenticate", "false" );
System.setProperty("com.sun.management.jmxremote.ssl", "false" );
System.setProperty("com.sun.management.jmxremote.port", "9995"  );

but it doesn't work. Any idea why?

By the time your code is called you've missed your chance to configure the jmxremote connector.

What you need to do is create your own rmi registry and a JMXConnectorServer to listen for rmi calls and pass them to the MBeanServer.

private void createJmxConnectorServer() throws IOException {
    LocateRegistry.createRegistry(1234);
    MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
    JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://localhost/jndi/rmi://localhost:1234/jmxrmi");
    JMXConnectorServer svr = JMXConnectorServerFactory.newJMXConnectorServer(url, null, mbs);
    svr.start();
}
