Custom MsgExchange Listener and JMX
I've written an exchange-listener that also extends BaseSystemService
and implements its own MBean interface (which extends from
LifeCycleMBean). I want to have basic manageability of this custom
service. My config is simply:
<sm:listeners>
<cmsm:clairmailMessageLogger />
</sm:listeners>
The listener registers fine and that part of it works, however, I
also want it to be container aware and register as an MBean, this
part does not work. I'm sure this is actually more of a JMX question,
but can anyone provide insight into how I would configure such a
MBean to plug into the smix jmx infrastructure?
Thanks,
BJ.

This should be now fixed in svn head.
Let me know if there is any problem.

Guillaume,
Thank you for your help. Sorry to be such a bother. I've implemented
as you've suggested, I am getting the container set, and once I have
it, I am calling init.
I think I am now encountering a 'timing' issue. I am still including
my object as a 'listener' in the config file. It appears that my
'init' is being called before the 'init' of the management context,
as I am getting a null pointer:
org.springframework.beans.MethodInvocationException: Property
'listeners' threw exception; nested exception is
java.lang.NullPointerException: null
java.lang.NullPointerException
at
org.apache.servicemix.jbi.management.ManagementContext.createObjectNameP
rops(ManagementContext.java:441)
at
org.apache.servicemix.jbi.management.ManagementContext.createObjectName(
ManagementContext.java:369)
at
org.apache.servicemix.jbi.management.ManagementContext.registerSystemSer
vice(ManagementContext.java:565)
at
org.apache.servicemix.jbi.management.BaseSystemService.init
(BaseSystemService.java:51)
at
com.clairmail.extensions.servicemix.ClairmailMessageLogger.setContainer(
ClairmailMessageLogger.java:69)
line 441 in management context is:
result.put("ContainerName", container.getName());
so it would appear that 'container' has not yet been set. Forgive
what may be a dumb question, is there a way to set dependency or
ordering such that my object doesn't get inited until everything else
has been inited? Is there a better way to approach this?
Thanks again,
BJ.

You will also need to implement the
org.apache.servicemix.jbi.container.ContainerAware interface and call
the init method when you receive the container object.

Actually, all the needed code is already in the BaseSystemService class.
You just have to call init(JBIContainer) and shutDown() and the
service will register / unregister itself as a JMX MBean.
