Hi,
yes, I have found that post two days ago... after several hours figuring out myself :-(
what I did after that:
I got MBeanNotCompliant, since the lifecycleinterceptor seems to be missing the
default constructor, so I added
public LifeCycleInterceptor() {
super();
this.log = Logger.getLogger(this.getClass());
} // just to have a logger, else will result in a null pointer in the invoke()
In NukesBuilder I changed
Descriptor mbeanDesc = resourceInfo.getDescriptor(null,
ModelMBeanConstants.MBEAN_DESCRIPTOR);
to:
Descriptor mbeanDesc = resourceInfo.getMBeanDescriptor();
since in getDescriptor you can not have null as a first parameter:
public Descriptor getDescriptor(String inDescriptorName,
String inDescriptorType)
throws MBeanException, RuntimeOperationsException {
if (inDescriptorName==null) { throw new RuntimeOperationsException(new
IllegalArgumentException("Descriptor is invalid"),
("Exception occurred trying
to set the descriptors of the MBeanInfo"));
}
But I don't know if I took the correct function
And in LifeCycleManager I added the (missing) getNext() function (from
AbstractInterceptor) and replaced all the getNext().invoke(incovation) with a call to
that:
// copied from AbstractInterceptor
private Object getNext(Invocation invocation) throws Throwable{
Interceptor ic = invocation.nextInterceptor();
// if the invocation object does not provide us with more interceptors,
// invoke the dispatcher that lands the invocation to its final target
// in the resource object
if (ic == null)
return invocation.dispatch();
// see if the next interceptor in the chain is shared
if (ic.isShared())
{
// we require a common interface for all shared interceptors
SharedInterceptor shared = (SharedInterceptor)ic;
// we invoke shared interceptor it via the MBean server bus, get the
// interceptors view to its MBean server
MBeanServer server = shared.getMBeanServer();
// And the object name the interceptor is registered under
ObjectName name = shared.getObjectName();
return server.invoke(
name, "invoke",
new Object[] { invocation }, // args
new String[] { Invocation.class.getName() } // signature
);
}
// invoke non-shared interceptor directly via Java reference
else
{
return ic.invoke(invocation);
}
}
... ending up with the following exceptions:
Caused by: java.lang.Exception: org.jboss.util.UnreachableStatementException: in
voke

ava:112)

So, I don't exactly know what I am doing here, since I am into the JMX stuff since two
days (beginning to understand how that ModelMBean works) and have a hard time figuring
out what the hell you guys are doing with that interceptor/invoker stuff...
