Interface: javax.management.MBeanServer (java/j2se/1.6) javadoc api

Interface: javax.management.MBeanServer

public interface MBeanServer
extends MBeanServerConnection

This is the interface for MBean manipulation on the agent side. It contains the methods necessary for the creation, registration, and deletion of MBeans as well as the access methods for registered MBeans. This is the core component of the JMX infrastructure.

User code does not usually implement this interface. Instead, an object that implements this interface is obtained with one of the methods in the javax.management.MBeanServerFactory class.

Every MBean which is added to the MBean server becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBean server. A Java object cannot be registered in the MBean server unless it is a JMX compliant MBean.

When an MBean is registered or unregistered in the MBean server a MBeanServerNotification Notification is emitted. To register an object as listener to MBeanServerNotifications you should call the MBean server method addNotificationListener with ObjectName the ObjectName of the MBeanServerDelegate. This ObjectName is:
JMImplementation:type=MBeanServerDelegate.

An object obtained from the createMBeanServer or newMBeanServer methods of the javax.management.MBeanServerFactory class applies security checks to its methods, as follows.

First, if there is no security manager (System.getSecurityManager() is null), then an implementation of this interface is free not to make any checks.

Assuming that there is a security manager, or that the implementation chooses to make checks anyway, the checks are made as detailed below. In what follows, className is the string returned by javax.management.MBeanInfo.getClassName() for the target MBean.

If a security check fails, the method throws SecurityException.

For methods that can throw javax.management.InstanceNotFoundException, this exception is thrown for a non-existent MBean, regardless of permissions. This is because a non-existent MBean has no className.

For the invoke method, the caller's permissions must imply MBeanPermission(className, operationName, name, "invoke").
For the getAttribute method, the caller's permissions must imply MBeanPermission(className, attribute, name, "getAttribute").
For the getAttributes method, the caller's permissions must imply MBeanPermission(className, null, name, "getAttribute"). Additionally, for each attribute a in the javax.management.AttributeList, if the caller's permissions do not imply MBeanPermission(className, a, name, "getAttribute"), the MBean server will behave as if that attribute had not been in the supplied list.
For the setAttribute method, the caller's permissions must imply MBeanPermission(className, attrName, name, "setAttribute"), where attrName is attribute.getName().
For the setAttributes method, the caller's permissions must imply MBeanPermission(className, null, name, "setAttribute"). Additionally, for each attribute a in the javax.management.AttributeList, if the caller's permissions do not imply MBeanPermission(className, a, name, "setAttribute"), the MBean server will behave as if that attribute had not been in the supplied list.
For the addNotificationListener methods, the caller's permissions must imply MBeanPermission(className, null, name, "addNotificationListener").
For the removeNotificationListener methods, the caller's permissions must imply MBeanPermission(className, null, name, "removeNotificationListener").
For the getMBeanInfo method, the caller's permissions must imply MBeanPermission(className, null, name, "getMBeanInfo").
For the getObjectInstance method, the caller's permissions must imply MBeanPermission(className, null, name, "getObjectInstance").
For the isInstanceOf method, the caller's permissions must imply MBeanPermission(className, null, name, "isInstanceOf").
For the queryMBeans method, the caller's permissions must imply MBeanPermission(null, null, name, "queryMBeans"). Additionally, for each MBean that matches name, if the caller's permissions do not imply MBeanPermission(className, null, name, "queryMBeans"), the MBean server will behave as if that MBean did not exist.

Certain query elements perform operations on the MBean server. If the caller does not have the required permissions for a given MBean, that MBean will not be included in the result of the query. The standard query elements that are affected are javax.management.Query.attr(java.lang.String), javax.management.Query.attr(java.lang.String, java.lang.String), and javax.management.Query.classattr().
For the queryNames method, the checks are the same as for queryMBeans except that "queryNames" is used instead of "queryMBeans" in the MBeanPermission objects. Note that a "queryMBeans" permission implies the corresponding "queryNames" permission.
For the getDomains method, the caller's permissions must imply MBeanPermission(null, null, name, "getDomains"). Additionally, for each domain d in the returned array, if the caller's permissions do not imply MBeanPermission(null, null, new ObjectName("d:x=x"), "getDomains"), the domain is eliminated from the array. Here, x=x is any key=value pair, needed to satisfy ObjectName's constructor but not otherwise relevant.
For the getClassLoader method, the caller's permissions must imply MBeanPermission(className, null, loaderName, "getClassLoader").
For the getClassLoaderFor method, the caller's permissions must imply MBeanPermission(className, null, mbeanName, "getClassLoaderFor").
For the getClassLoaderRepository method, the caller's permissions must imply MBeanPermission(null, null, null, "getClassLoaderRepository").
For the deprecated deserialize methods, the required permissions are the same as for the methods that replace them.
For the instantiate methods, the caller's permissions must imply MBeanPermission(className, null, null, "instantiate").
For the registerMBean method, the caller's permissions must imply MBeanPermission(className, null, name, "registerMBean"). Here className is the string returned by javax.management.MBeanInfo.getClassName() for an object of this class.
If the MBeanPermission check succeeds, the MBean's class is validated by checking that its ProtectionDomain implies MBeanTrustPermission("register").

Finally, if the name argument is null, another MBeanPermission check is made using the ObjectName returned by MBeanRegistration.preRegister.
For the createMBean methods, the caller's permissions must imply the permissions needed by the equivalent instantiate followed by registerMBean.
For the unregisterMBean method, the caller's permissions must imply MBeanPermission(className, null, name, "unregisterMBean").

Methods

addNotificationListenertop

public void addNotificationListener(ObjectName name, NotificationListener listener, NotificationFilter filter, Object handback) throws InstanceNotFoundException

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.
Parameters:
@param name The name of the MBean on which the listener should be added.
@param listener The listener object which will handle the notifications emitted by the registered MBean.
@param filter The filter object. If filter is null, no filtering will be performed before handling notifications.
@param handback The context to be sent to the listener when a notification is emitted.
Exceptions:
@exception InstanceNotFoundException The MBean name provided does not match any of the registered MBeans.

addNotificationListenertop

public void addNotificationListener(ObjectName name, ObjectName listener, NotificationFilter filter, Object handback) throws InstanceNotFoundException

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.
Parameters:
@param name The name of the MBean on which the listener should be added.
@param listener The object name of the listener which will handle the notifications emitted by the registered MBean.
@param filter The filter object. If filter is null, no filtering will be performed before handling notifications.
@param handback The context to be sent to the listener when a notification is emitted.
Exceptions:
@exception InstanceNotFoundException The MBean name of the notification listener or of the notification broadcaster does not match any of the registered MBeans.

Parameters:
@param 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.
@param query The query expression to be applied for selecting MBeans. If null no query expression will be applied for selecting MBeans.
Return:
@return A set containing the ObjectNames for the MBeans selected. If no MBean satisfies the query, an empty list is returned.
