[jboss-dev-forums] [Design the new POJO MicroContainer] - Registering listener on KernelEventManager
I'm looking at providing a better startup notification as the current one from the
ServerImpl occurs just at the end of the bootstrap phase. I'm trying to test out an
example listener, but the following
| <deployment xmlns="urn:jboss:bean-deployer:2.0">
| <bean name="StartupMonitor"
|
class="org.jboss.test.profileservice.lib.startup.StartupMonitor">
| <install bean="jboss.kernel:service=KernelEventManager"
method="registerListener">
| <!-- registerListener(Object name, KernelEventListener listener,
KernelEventFilter filter, Object handback) -->
|
<parameter>jboss.kernel:service=KernelEventManager</parameter>
| <parameter><this/></parameter>
| <parameter><null/></parameter>
| <parameter><null/></parameter>
| </install>
| </bean>
| </deployment>
|
fails with an error like:
| 15:38:32,904 ERROR [AbstractKernelController] Error installing to Installed:
name=StartupMonitor state=Start
| java.lang.IllegalArgumentException: Cannot install, context
BeanKernelRegistryEntry@56d0a8c{target=org.jboss.kernel.plugins.event.AbstractEventManager(a)39cf701c}
does not implement InvokeDispatchContext

Why wouldn't the event mgr have an InvokeDispatchContext implementation?
