Class ChainedMBeanServerBuilder

java.lang.Object
  javax.management.MBeanServerBuilder
      mx4j.server.ChainedMBeanServerBuilder

public class ChainedMBeanServerBuilder

extends javax.management.MBeanServerBuilder

Base class for chained MBeanServerBuilders.
By default this class delegates all method calls to the nested MBeanServerBuilder.
See the MX4J documentation on how to use correctly this class.

Example implementation:

 public class LoggingBuilder extends ChainedMBeanServerBuilder
 {
    public LoggingBuilder()
    {
       super(new MX4JMBeanServerBuilder());
    }
 

    public MBeanServer newMBeanServer(String defaultDomain, MBeanServer outer, MBeanServerDelegate delegate)
    {
       LoggingMBeanServer external = new LoggingMBeanServer();
       MBeanServer nested = getBuilder().newMBeanServer(defaultDomain, outer == null ? external : outer, delegate);
       external.setMBeanServer(nested);
       return external;
    }
 }
 

 public class LoggingMBeanServer extends ChainedMBeanServer
 {
    protected void setMBeanServer(MBeanServer server)
    {
       super.setMBeanServer(server);
    }
 

    public Object getAttribute(ObjectName objectName, String attribute)
            throws MBeanException, AttributeNotFoundException, InstanceNotFoundException, ReflectionException
    {
       Object value = super.getAttribute(objectName, attribute);
       System.out.println("Value is: " + value);
       return value;
    }
 

    ...
 }
