      • createMBean

        ObjectInstance createMBean(String className,
                                   ObjectName name)
                            throws ReflectionException,
                                   InstanceAlreadyExistsException,
                                   MBeanRegistrationException,
                                   MBeanException,
                                   NotCompliantMBeanException

        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).

        If this method successfully creates an MBean, a notification is sent as described above.

        Specified by:
        createMBean in interface MBeanServerConnection
        Parameters:
        className - The class name of the MBean to be instantiated.
        name - The object name of the MBean. May be null.
        Returns:
        An ObjectInstance, containing the ObjectName and the Java class name of the newly instantiated MBean. If the contained ObjectName is n, the contained Java class name is getMBeanInfo(n).getClassName().
        Throws:
        RuntimeOperationsException - Wraps a java.lang.IllegalArgumentException: The className passed in parameter is null, the ObjectName passed in parameter contains a pattern or no ObjectName is specified for the MBean.
        RuntimeMBeanException - If the MBean's constructor or its preRegister or postRegister method threw a RuntimeException. If the postRegister (MBeanRegistration interface) method of the MBean throws a RuntimeException, the createMBean method will throw a RuntimeMBeanException, although the MBean creation and registration succeeded. In such a case, the MBean will be actually registered even though the createMBean method threw an exception. Note that RuntimeMBeanException can also be thrown by preRegister, in which case the MBean will not be registered.
        RuntimeErrorException - If the postRegister (MBeanRegistration interface) method of the MBean throws an Error, the createMBean method will throw a RuntimeErrorException, although the MBean creation and registration succeeded. In such a case, the MBean will be actually registered even though the createMBean method threw an exception. Note that RuntimeErrorException can also be thrown by preRegister, in which case the MBean will not be registered.
        ReflectionException - Wraps a java.lang.ClassNotFoundException or a java.lang.Exception that occurred when trying to invoke the MBean's constructor.
        InstanceAlreadyExistsException - The MBean is already under the control of the MBean server.
        MBeanRegistrationException - The preRegister (MBeanRegistration interface) method of the MBean has thrown an exception. The MBean will not be registered.
        MBeanException - The constructor of the MBean has thrown an exception
        NotCompliantMBeanException - This class is not a JMX compliant MBean

                                        QueryExp query)
        Gets MBeans controlled by the MBean server. This method allows any of the following to be obtained: All MBeans, a set of MBeans specified by pattern matching on the ObjectName and/or a Query expression, a specific MBean. When the object name is null or no domain and key properties are specified, all objects are to be selected (and filtered if a query is specified). It returns the set of ObjectInstance objects (containing the ObjectName and the Java Class name) for the selected MBeans.
        Specified by:
        queryMBeans in interface MBeanServerConnection
        Parameters:
        name - The object name pattern identifying the MBeans to be retrieved. If null or no domain and key properties are specified, all the MBeans registered will be retrieved.
        query - The query expression to be applied for selecting MBeans. If null no query expression will be applied for selecting MBeans.
        Returns:
        A set containing the ObjectInstance objects for the selected MBeans. If no MBean satisfies the query an empty list is returned.
        Throws:
        RuntimeOperationsException
      • queryNames

        Set<ObjectName> queryNames(ObjectName name,
                                   QueryExp query)
        Gets the names of MBeans controlled by the MBean server. This method enables any of the following to be obtained: The names of all MBeans, the names of a set of MBeans specified by pattern matching on the ObjectName and/or a Query expression, a specific MBean name (equivalent to testing whether an MBean is registered). When the object name is null or no domain and key properties are specified, all objects are selected (and filtered if a query is specified). It returns the set of ObjectNames for the MBeans selected.
        Specified by:
        queryNames in interface MBeanServerConnection
        Parameters:
        name - The object name pattern identifying the MBean names to be retrieved. If null or no domain and key properties are specified, the name of all registered MBeans will be retrieved.
        query - The query expression to be applied for selecting MBeans. If null no query expression will be applied for selecting MBeans.
        Returns:
        A set containing the ObjectNames for the MBeans selected. If no MBean satisfies the query, an empty list is returned.
        Throws:

        Description copied from interface: MBeanServerConnection

        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);
         }
         
        Specified by:
        getAttributes in interface MBeanServerConnection
        Parameters:
        name - The object name of the MBean from which the attributes are retrieved.
        attributes - A list of the attributes to be retrieved.
        Returns:
        The list of the retrieved attributes.
        Throws:
        RuntimeOperationsException - Wrap a java.lang.IllegalArgumentException: The object name in parameter is null or attributes in parameter is null.
        InstanceNotFoundException - The MBean specified is not registered in the MBean server.
        ReflectionException - An exception occurred when trying to invoke the getAttributes method of a Dynamic MBean.

        Description copied from interface: MBeanServerConnection

        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);
         }
         
        Specified by:
        setAttributes in interface MBeanServerConnection
        Parameters:
        name - The object name of the MBean within which the attributes are to be set.
        attributes - A list of attributes: The identification of the attributes to be set and the values they are to be set to.
        Returns:
        The list of attributes that were set, with their new values.
        Throws:
        RuntimeOperationsException - Wraps a java.lang.IllegalArgumentException: The object name in parameter is null or attributes in parameter is null.
        InstanceNotFoundException - The MBean specified is not registered in the MBean server.
        ReflectionException - An exception occurred when trying to invoke the getAttributes method of a Dynamic MBean.

        Object invoke(ObjectName name,
                      String operationName,
                      Object[] params,
                      String[] signature)
               throws InstanceNotFoundException,
                      MBeanException,
                      ReflectionException
        Description copied from interface: MBeanServerConnection

        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);
         
        Specified by:
        invoke in interface MBeanServerConnection
        Parameters:
        name - The object name of the MBean on which the method is to be invoked.
        operationName - The name of the operation to be invoked.
        params - An array containing the parameters to be set when the operation is invoked
        signature - An array containing the signature of the operation, an array of class names in the format returned by Class.getName(). The class objects will be loaded using the same class loader as the one used for loading the MBean on which the operation was invoked.
        Returns:
        The object returned by the operation, which represents the result of invoking the operation on the MBean specified.
        Throws:
        InstanceNotFoundException - The MBean specified is not registered in the MBean server.
        MBeanException - Wraps an exception thrown by the MBean's invoked method.
        ReflectionException - Wraps a java.lang.Exception thrown while trying to invoke the method.

        String[] getDomains()
        Description copied from interface: MBeanServerConnection

        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.

        Specified by:
        getDomains in interface MBeanServerConnection

        the list of domains.
      • isInstanceOf

        boolean isInstanceOf(ObjectName name,
                             String className)
                      throws InstanceNotFoundException
        Description copied from interface: MBeanServerConnection

        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.

        Specified by:
        isInstanceOf in interface MBeanServerConnection
        Parameters:
        name - The ObjectName of the MBean.
        className - The name of the class.
        Returns:
        true if the MBean specified is an instance of the specified class according to the rules above, false otherwise.
        Throws:
        InstanceNotFoundException - The MBean specified is not registered in the MBean server.
