/**
* This example shows the simplest way to connect to a JSR 160 connector server. <br />
* To do so, the most important information is the JMXServiceURL, which is the address
* of the remote connector server. This url is generated by the server, and
* must be known to the client.
* When using JSR 160's RMI connector server, this information is often in form of a
* JNDI name where the RMI stub has been registered; in this case the client needs
* to know the host and port of the JNDI server and the JNDI path where the stub is
* registered.
