Access to MBean Attributes

An AMX MBean Attribute is accessible in three ways:

• Dotted names via MonitoringDottedNames and ConfigDottedNames

• Attributes on MBeans via getAttribute(s) and setAttributes(s) (from the standard JMX API)

• Getters/setters within the MBean’s interface class, for example, getPort(), setPort(), and so on.

All dotted names that are accessible via the command line interface are available as Attributes within a single MBean. This includes properties, which are Attributes beginning with the prefix property., for example, server.property.myproperty.

Certain attributes that may be of a specific type, such as int, are declared as java.lang.String. This is because the value of the attribute may be a template of a form such as ${HTTP_LISTENER_PORT}.

An application or module MBean has two enabled attributes. To get the correct state of the application or module, look up the enabled attribute under the application-ref.

To look up an application-ref in JConsole, select the following:

com.sun.appserv -> application-ref -> app-or-module-name -> server -> config

The attributes, including enabled, are listed under config.
