Missing Websphere NodeAgent JMX MBean

I am trying to run the sample code from IBM (sample code link) to connect to Websphere Application Server v7.0 through a JMX client.

I could suc开发者_开发问答cessfully connect to the Websphere MBeanServer by jconsole, and could see two domains exist (JMImplementation and WebSphere). However, I found that there is no NodeAgent MBean as specified in the sample code with ObjectName pattern WebSphere:type=NodeAgent,node=<some node>,*.

Does anybody know why the NodeAgent MBean is not there?

You can run such query "WebSphere:*" - so you will get all mbeans you have in time of query evaluated. Just print it out to get expression what you actually have. For example i have only server and portal mbeans in my configuration and no nodeAgent. So this sample will not work in my environment too.

Which edition of WebSphere are you running? WebSphere Express does not include node agents or a deployment manager. WebSphere Network Deployment includes these components to support a variety of features. It's filled with marketing speak, but IBM has a PDF listing high-level differences between the various editions.
