Yes, Sergey.
I am trying to do this, but so far, can't get rid of the replying on must have
@XmlRootElement annotation for ObjectName. Probably, I need to create some
testing purpose mbeans, register to InstrumentationManagerImpl, and see how
they work.
@XmlRootElement
public class ObjectNameCollection {
private Set<ObjectName> endPointNames;
@XmlElement(name="endpoint")
@XmlElementWrapper(name="endpoints")
public Set<ObjectName> getEndPointNames() {
return endPointNames;
}
public void setEndPointNames(Set<ObjectName> endPointNames) {
this.endPointNames = endPointNames;
}
}
@GET
@Path("/list")
public ObjectNameCollection list() throws IOException,
MalformedObjectNameException, NullPointerException{
JMXServiceURL url = new JMXServiceURL(jmxServerURL);
JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
mbsc = jmxc.getMBeanServerConnection();
ObjectName queryEndpointName = new
ObjectName(ManagementConstants.DEFAULT_DOMAIN_NAME +
":type=Bus.Service.Endpoint,*");
Set<ObjectName> endpointNames =
CastUtils.cast(mbsc.queryNames(queryEndpointName, null));
ObjectNameCollection objNameCollection = new ObjectNameCollection();
objNameCollection.setEndPointNames(endpointNames);
Iterator<ObjectName> it = endpointNames.iterator();
while(it.hasNext()){
ObjectName objectName = it.next();
System.out.println("CanonicalName =
"+objectName.getCanonicalName());
System.out.println("Domain = "+objectName.getDomain());
}
return objNameCollection;
}
Another question is, are these all the cxf registered mbeans, (In All known
Implementing Classes) ?
org.apache.cxf.management
Interface ManagedComponent
All Known Subinterfaces:
Counter
All Known Implementing Classes:
ManagedBus, ManagedEndpoint, PerformanceCounter, ResponseTimeCounter,
WorkQueueImplMBeanWrapper, WorkQueueManagerImplMBeanWrapper
