[newbie question] some question about MBean and notification

Hi,

I would suggest you look into MXBeans. Here are three articles that will probably help you:

javax.management.StandardMBean: When and Why.

Hi,

An OpenMBean is just an MBean that has a ModelMBeanInfo, and uses only simple types

as defined by javax.management.openmbean.

You can use OpenMBeans to manage your resource, but if you don't have MXBeans

then you will need to write your OpenMBean by hand. This is not very difficult but

is a bit tedious.

There should be a chapter on OpenMBeans in the JMX tutorial - have a look at it.

http://blogs.sun.com/jmxetc/entry/looking_for_jmx_overview_examples

To send a notification with a RequiredModelMBean just use its sendNotification() method.

http://java.sun.com/j2se/1.5.0/docs/api/javax/management/modelmbean/ModelMBeanNotificationBroadcaster.html#sendNotification(javax.management.Notification)

With a "generated ModelMBean" I don't know - I assume it depends on how and by what

it was generated and whether it is a subclass of javax.management.modelmbean.RequiredModelMBean.

You will need to look at the generated code to figure it out.

Hope this helps,
