Dynamic registration of mbeans
I have some code i am testing for a future application that needs to instantiate new instances of an mbeans and register them with the server.
my test code runs up the mbean ok, but as soon as i put the registration code to add a new instance to the server it failes.
Does anyone know what i am doing wrong ????
Interface:
package com.flytxt.transport.jmx;
import org.jboss.annotation.ejb.Management;
@Management
public interface TransportServer extends org.jboss.system.Service{
public void start();
public void stop();
public void destroy();
public void create();
public boolean pause();
}
Mbean:
package com.flytxt.transport.jmx;
import javax.management.InstanceNotFoundException;
import javax.management.MBeanRegistrationException;
import javax.management.MBeanServer;
import javax.management.MalformedObjectNameException;
import javax.management.ObjectName;
import org.jboss.annotation.ejb.Service;
import org.jboss.mx.util.MBeanProxyExt;
import org.jboss.mx.util.MBeanServerLocator;
@Service (objectName="flytxt:service=transportServer")
public class TransportServerMBean implements TransportServer {
private boolean running = false;
private MBeanServer server = null;
private TransportServer oi = null;
public TransportServerMBean() {
System.out.println("TransportServerMbean instanciated");
}
public void start() {
if (! running) {
System.out.println("TransportServerMbean started");
running = true;
try {
oi = (TransportServer) MBeanProxyExt.create(this.getClass(),new ObjectName("flytxt:service=transportServer2"), server);
} catch (MalformedObjectNameException e) {
e.printStackTrace();
running = false;
} catch (NullPointerException e) {
e.printStackTrace();
running = false;
}
} else {
System.out.println("TransportServerMbean already started");
}
}
public void stop() {
if (running) {
System.out.println("TransportServerMbean stopped");
running = false;
try {
oi.pause();
server.unregisterMBean(new ObjectName("flytxt:service=transportServer2"));
} catch (InstanceNotFoundException e) {
e.printStackTrace();
running = true;
} catch (MBeanRegistrationException e) {
e.printStackTrace();
running = true;
} catch (MalformedObjectNameException e) {
e.printStackTrace();
running = true;
} catch (NullPointerException e) {
e.printStackTrace();
running = true;
}
} else {
System.out.println("TransportServerMbean not running");
}
}
public void destroy() {
System.out.println("TransportServerMbean destroyed");
}
public void create() {
server = MBeanServerLocator.locate();
System.out.println("TransportServerMbean created");
}
public boolean pause() {
System.out.println("TransportServerMbean paused");
return true;
}
}
the error i get from this is

I tried calling server.create but it kept giving me a javax.management.NotCompliantMBeanException: Class does not expose a management interface: java.lang.Object
