#### Editing a Custom MBean

In the Edit custom MBean page, you can modify the properties and attributes of a Custom MBean.

- Name field displays the name of the Custom MBean. This information cannot be edited.

- Implementation Class Name field displays the Implementation Class Name of the Custom MBean. This information cannot be edited.

- Object Name field displays the `javax.management.ObjectName` of the MBean. The `ObjectName` must be unique within the target specified, as is the case with the name of the MBean. The uniqueness is required because at runtime the MBeans are registered with their `ObjectName` and not names.

  The default ObjectName is of the format: `user:type= implementation-class-name,name=implementation-class-name`. The `user` is the name of the JMX Domain where these MBeans will be registered. No other JMX domain name is allowed.

  This is the `ObjectName` that will be stored in the Application Server domain's configuration. At runtime though, when the MBean is registered in the MBeanServer, an identifying property, `server=name_of_the_target_server_instance` is inserted in the `ObjectName`.

  This property is not persisted. It is a runtime artifact only.

- In the Description field, you can provide a brief description for the Custom MBean.

- Status indicates if the Custom MBean is enabled.

- The Attributes table lists the attributes available for this MBean. You may edit the attribute values, if required.

- Click Save for your changes to take effect.
