9.1.1 Connector Server Factories

The simplest way to create connector servers is to use the JMXConnectorServerFactory constructor defined by JMX Remote API. No instances of this class are ever created, but its single method, newJMXConnectorServer() is called to create instances of the JMXConnectorServer class. New JMXConnectorServer instances are created when newJMXConnectorServer() is passed the following parameters:

1. A JMXServiceURL, that serves as the address for the connector server; this URL identifies the connector protocol to be implemented, and the machine name and port number (or path or URL) at which this connector server will be bound.

2. The environment Map for newJMXConnectorServer(); this can be null.

3. A reference to the MBean server that will be exposed for remote management through this connector server. If null is given at creation time, the MBean server that will be exposed to remote management will be the MBean server in which the connector server is later registered as an MBean.

   Note that if you supply an MBean server at creation time, you can optionally register the connector server as an MBean. In that case, the MBean server in which you choose to register the connector server can optionally be the same MBean server as the one that was supplied at creation time. However, if you supply a null value for this parameter, you will need to register the connector server as an MBean in the MBean server that you wish to expose through that connector server.

In the JMXServiceURL, the connector protocol specified can be either RMI or JMXMP. Depending which protocol is specified, the connector server created will be either an instance of the RMIConnectorServer or JMXMPConnectorServer classes. Both of these classes inherit from the JMXConnectorServer class.
