+When setting up a JMX connection, the host name must duplicate the one specified in the -Djava.rmi.server.hostname paremeter of the application startup.sh script
+(i.e. one cannot use the server IP - the hostname has got to be precisely the same).
+Note: **Ensure** you have the names in your hosts file for the connection to be successful (**won't work otherwise**).
