How do I represent an XML file as a Java object using commons-digester

<MyConfig>
    <ServerName>nile</ServerName>
    <ServerPort>8079</ServerPort>
</MyConfig>

        digester.setValidating(false);

        digester.addObjectCreate("MyConfig", MyConfig.class);

        digester.addCallMethod("MyConfig/ServerName", "setServerName", 0);
        digester.addCallMethod("MyConfig/ServerPort", "setServerPort", 0);

        System.out.println("Creating MyConfig...");
        MyConfig mc = (MyConfig) digester.parse(new File(configFile));
        System.out.println("Done.");

        System.out.println("Port: " + mc.getServerName());
