New subject: [JBoss-dev] AbstractKernelController behavior inconsistent

Wednesday, 23 August 2006

Can I set an attribute on a JMX service that has been created but failed
to start (ServiceContext state is FAILED)?

Sorry.  I can make ServiceProxy transient myself.  I thought it was in
the mc code.

I will make the fix and check the updated testcase.

I can check in the updated test case once the ServiceProxy is made
transient. Can you make the fix?

 Should ServiceProxy be serializable?

No, the old one wasn't either, since it holds a link to the
MBeanServer (via the ServiceController) 
not an MBeanServerConnection (remote version).

The ServiceContext should be, so the ServiceProxy
inside it should be transient. i.e. not part of the
serialized form. 

But this looks like a bug that has been there forever.

...

 Caused by: java.io.NotSerializableException:

 for:

 ServiceControllerMBean scmb = (ServiceControllerMBean)

           MBeanServerInvocationHandler.newProxyInstance(server,
 ServiceControllerMBean.OBJECT_NAME,

                 ServiceControllerMBean.class, false);

 and also for:

 ServiceContext sc = (ServiceContext)server.invoke(so,
 "getServiceContext",new Object[]{serviceOName}, 

               new String[]{"javax.management.ObjectName"});

 Why cannot ServiceContext be an attribute on the
 ServiceControllerMBean(feature request?)

How can it be an attribute, it takes a parameter?

...

 Basically, when the ServiceController has entered the Error state for
 a service, then I get the state of the service (after
 unregister->create->start) is the state "REGISTERED" (instead of
 Started)

I don't understand this? You cannot transistion from
unregistered to create. Once it is unregistered it doesn't exist.

Provide a complete example so we don't have to guess what you
talking about.
