Instantiates and registers an MBean in the MBean server. The MBean server will use its Default Loader Repository to load the class of the MBean. An object name is associated with the MBean. If the object name given is null, the MBean must provide its own name by implementing the MBeanRegistration interface and returning the name from the preRegister method.

This method is equivalent to createMBean(className, name, (Object[]) null, (String[]) null).

Instantiates and registers an MBean in the MBean server. The class loader to be used is identified by its object name. An object name is associated with the MBean. If the object name of the loader is null, the ClassLoader that loaded the MBean server will be used. If the MBean's object name given is null, the MBean must provide its own name by implementing the MBeanRegistration interface and returning the name from the preRegister method.

This method is equivalent to createMBean(className, name, loaderName, (Object[]) null, (String[]) null).

Instantiates and registers an MBean in the MBean server. The class loader to be used is identified by its object name. An object name is associated with the MBean. If the object name of the loader is not specified, the ClassLoader that loaded the MBean server will be used. If the MBean object name given is null, the MBean must provide its own name by implementing the MBeanRegistration interface and returning the name from the preRegister method.

Retrieves the values of several attributes of a named MBean. The MBean is identified by its object name.

If one or more attributes cannot be retrieved for some reason, they will be omitted from the returned AttributeList. The caller should check that the list is the same size as the attributes array. To discover what problem prevented a given attribute from being retrieved, call getAttribute for that attribute.

Here is an example of calling this method and checking that it succeeded in retrieving all the requested attributes:

 String[] attrNames = ...;
 AttributeList list = mbeanServerConnection.getAttributes(objectName, attrNames);
 if (list.size() == attrNames.length)
     System.out.println("All attributes were retrieved successfully");
 else {
     List<String> missing = new ArrayList<String>(Arrays.asList(attrNames));
     for (Attribute a : list.asList())
         missing.remove(a.getName());
     System.out.println("Did not retrieve: " + missing);
 }
 

Sets the values of several attributes of a named MBean. The MBean is identified by its object name.

If one or more attributes cannot be set for some reason, they will be omitted from the returned AttributeList. The caller should check that the input AttributeList is the same size as the output one. To discover what problem prevented a given attribute from being retrieved, it will usually be possible to call setAttribute for that attribute, although this is not guaranteed to work. (For example, the values of two attributes may have been rejected because they were inconsistent with each other. Setting one of them alone might be allowed.)

Here is an example of calling this method and checking that it succeeded in setting all the requested attributes:

 AttributeList inputAttrs = ...;
 AttributeList outputAttrs = mbeanServerConnection.setAttributes(objectName, inputAttrs);
 if (inputAttrs.size() == outputAttrs.size())
     System.out.println("All attributes were set successfully");
 else {
     List<String> missing = new ArrayList<String>();
     for (Attribute a : inputAttrs.asList())
         missing.add(a.getName());
     for (Attribute a : outputAttrs.asList())
         missing.remove(a.getName());
     System.out.println("Did not set: " + missing);
 }
 

Invokes an operation on an MBean.

Because of the need for a signature to differentiate possibly-overloaded operations, it is much simpler to invoke operations through an MBean proxy where possible. For example, suppose you have a Standard MBean interface like this:

 public interface FooMBean {
     public int countMatches(String[] patterns, boolean ignoreCase);
 }
 

The countMatches operation can be invoked as follows:

 String[] myPatterns = ...;
 int count = (Integer) mbeanServerConnection.invoke(
         objectName,
         "countMatches",
         new Object[] {myPatterns, true},
         new String[] {String[].class.getName(), boolean.class.getName()});
 

Alternatively, it can be invoked through a proxy as follows:

 String[] myPatterns = ...;
 FooMBean fooProxy = JMX.newMBeanProxy(
         mbeanServerConnection, objectName, FooMBean.class);
 int count = fooProxy.countMatches(myPatterns, true);
 

Returns the list of domains in which any MBean is currently registered. A string is in the returned array if and only if there is at least one MBean registered with an ObjectName whose getDomain() is equal to that string. The order of strings within the returned array is not defined.

Adds a listener to a registered MBean. Notifications emitted by the MBean will be forwarded to the listener.

Adds a listener to a registered MBean.

A notification emitted by an MBean will be forwarded by the MBeanServer to the listener. If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.

The listener object that receives notifications is the one that is registered with the given name at the time this method is called. Even if it is subsequently unregistered, it will continue to receive notifications.

If the listener is registered more than once, perhaps with different filters or callbacks, this method will remove all those registrations.

Removes a listener from a registered MBean.

The MBean must have a listener that exactly matches the given listener, filter, and handback parameters. If there is more than one such listener, only one is removed.

The filter and handback parameters may be null if and only if they are null in a listener to be removed.

Removes a listener from a registered MBean.

If the listener is registered more than once, perhaps with different filters or callbacks, this method will remove all those registrations.

Removes a listener from a registered MBean.

The MBean must have a listener that exactly matches the given listener, filter, and handback parameters. If there is more than one such listener, only one is removed.

The filter and handback parameters may be null if and only if they are null in a listener to be removed.

Returns true if the MBean specified is an instance of the specified class, false otherwise.

If name does not name an MBean, this method throws InstanceNotFoundException.

Otherwise, let
X be the MBean named by name,
L be the ClassLoader of X,
N be the class name in X's MBeanInfo.

If N equals className, the result is true.

Otherwise, if L successfully loads className and X is an instance of this class, the result is true.

Otherwise, if L successfully loads both N and className, and the second class is assignable from the first, the result is true.

Otherwise, the result is false.
