Managing MBeans Using the Visual
Administrator
Use
The administration of the J2EE Engine is based on the JMXTM standard. For every component managed by the Visual Administrator there is a corresponding MBean registered in the cluster. For components (cluster elements, services, managers, libraries, and interfaces), the Visual Administrator provides standard views. For Mbeans that do not represent an element of these groups, the Visual Administrator provides a generic view that provides information about the management operations and attributes that these MBeans expose. This view allows attributes and operations to be listed, the values of the attributes to be set, and operations to be invoked on the MBeans.
Prerequisites
To display an MBean in the Visual Administrator, first you have to modify the source code of your MBean. For more information, see the Displaying MBeans in the Visual Administrator section of the Registering MBeans document in the Development Manual.
Procedure
The MBean is displayed as a separate node in the Visual Administrator tree, right after the J2EE Engine components.
...
1. Select the MBean from the Visual Administrator tree.
The MBean’s properties are displayed in the right-hand pane.
