The JMXBookAgent class imports the com.sun.jdmk.comm package in order to
obtain the RmiConnectorServer class. It contains the classes contributed by Sun
Microsystems in Sun's JMX RI .
The class uses the default constructor of the RmiConnectorServer class. The
constructor tells the server to use the default port and service name. However, as
mentioned previously, this is not the RmiConnectorServer class's only constructor.
Table 9.1 lists the constructors and their arguments.

Table 9.1 The constructors of the RmiConnectorServer class

Constructor Description

The default constructor

RmiConnectorServer()

Specifies a new port for binding to an RMI registry

RmiConnectorServer( int port )

Specifies a name for the object registered on the
RMI registry

RmiConnectorServer( String name)

Specifies both a new registry port and new remote
object name

RmiConnectorServer( int port,
String name)

By using one of the other constructors, you can control the RMI registry the
server will bind to, and you can change the name of the remote object that will
be registered on the registry.

9.2.3 Connecting to the RMI server

Now that we have examined a basic agent that uses an RMI connector, let's look
at the RMI connector client contained in the class RmiConnectorClient . As men-
tioned earlier, this class declares methods that correspond to every method
