In JBoss 6 M4 the JMXConnector defined in jmx-jboss-beans.xml (org.jboss.system.server.jmx.JMXConnector) does not allow to use SSL although this can be done with standard Java JMX over RMI classes. The SocketFactories are hard coded:

         DefaultClientSocketFactory clientSocketFactory = new DefaultClientSocketFactory();
         clientSocketFactory.setBindAddress(hostname);
         DefaultSocketFactory serverSocketFactory = new DefaultSocketFactory();
         serverSocketFactory.setBindAddress(hostname);
         registry = LocateRegistry.createRegistry(rmiRegistryPort, clientSocketFactory, serverSocketFactory);

Since credentials and other sensitive data are sent over the wire, using SSL should be possible without writing your own JMXConnector.

Thanks, Harald

Attached a changed implementation being SSL enabled. The connection factories are set as properties of the MC bean

The following property has to be specified on the JMX client:

com.sun.jndi.rmi.factory.socket=javax.rmi.ssl.SslRMIClientSocketFactory
