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 {@link 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 {@link javax.management.MBeanServerNotification
* MBeanServerNotification} Notification is emitted. To register an
* object as listener to MBeanServerNotifications you should call the
* MBean server method {@link #addNotificationListener
* addNotificationListener} with ObjectName
the
* ObjectName
of the {@link
* javax.management.MBeanServerDelegate MBeanServerDelegate}. This
* ObjectName
is:
* JMImplementation:type=MBeanServerDelegate
.
An object obtained from the {@link * MBeanServerFactory#createMBeanServer(String) createMBeanServer} or * {@link MBeanServerFactory#newMBeanServer(String) newMBeanServer} * methods of the {@link MBeanServerFactory} class applies security * checks to its methods, as follows.
* *First, if there is no security manager ({@link * 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 {@link MBeanInfo#getClassName()} for the target
* MBean.
If a security check fails, the method throws {@link * SecurityException}.
* *For methods that can throw {@link 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 {@link #invoke invoke} method, the caller's * permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, operationName, name, "invoke")}.
* *For the {@link #getAttribute getAttribute} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, attribute, name, "getAttribute")}.
* *For the {@link #getAttributes getAttributes} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "getAttribute")}. * Additionally, for each attribute a in the {@link * AttributeList}, if the caller's permissions do not imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, a, name, "getAttribute")}, the * MBean server will behave as if that attribute had not been in the * supplied list.
* *For the {@link #setAttribute setAttribute} method, the
* caller's permissions must imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(className, attrName, name, "setAttribute")}, where
* attrName
is {@link Attribute#getName()
* attribute.getName()}.
For the {@link #setAttributes setAttributes} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "setAttribute")}. * Additionally, for each attribute a in the {@link * AttributeList}, if the caller's permissions do not imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * 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 {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(className, null, name,
* "addNotificationListener")}.
For the removeNotificationListener
methods,
* the caller's permissions must imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(className, null, name,
* "removeNotificationListener")}.
For the {@link #getMBeanInfo getMBeanInfo} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "getMBeanInfo")}.
* *For the {@link #getObjectInstance getObjectInstance} method, * the caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "getObjectInstance")}.
* *For the {@link #isInstanceOf isInstanceOf} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "isInstanceOf")}.
* *For the {@link #queryMBeans queryMBeans} method, the
* caller's permissions must imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(null, null, name, "queryMBeans")}.
* Additionally, for each MBean that matches name
,
* if the caller's permissions do not imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* 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 {@link * Query#attr(String)}, {@link Query#attr(String,String)}, and {@link * Query#classattr()}.
* *For the {@link #queryNames 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 {@link #getDomains getDomains} method, the caller's
* permissions must imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(null, null, name, "getDomains")}. Additionally,
* for each domain d in the returned array, if the caller's
* permissions do not imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* 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 {@link #getClassLoader getClassLoader} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, loaderName, * "getClassLoader")}.
* *For the {@link #getClassLoaderFor getClassLoaderFor} method, * the caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, mbeanName, * "getClassLoaderFor")}.
* *For the {@link #getClassLoaderRepository * getClassLoaderRepository} method, the caller's permissions must * imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * 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 {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(className, null, null, "instantiate")}.
For the {@link #registerMBean registerMBean} method, the
* caller's permissions must imply {@link
* MBeanPermission#MBeanPermission(String,String,ObjectName,String)
* MBeanPermission(className, null, name, "registerMBean")}. Here
* className
is the string returned by {@link
* MBeanInfo#getClassName()} for an object of this class.
*
*
If the MBeanPermission
check succeeds, the MBean's
* class is validated by checking that its {@link
* java.security.ProtectionDomain ProtectionDomain} implies {@link
* MBeanTrustPermission#MBeanTrustPermission(String)
* MBeanTrustPermission("register")}.
Finally, if the name
argument is null, another
* MBeanPermission
check is made using the
* ObjectName
returned by {@link
* MBeanRegistration#preRegister MBeanRegistration.preRegister}.
For the createMBean
methods, the caller's
* permissions must imply the permissions needed by the equivalent
* instantiate
followed by
* registerMBean
.
For the {@link #unregisterMBean unregisterMBean} method, * the caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(className, null, name, "unregisterMBean")}.
* *For the {@link #isRegistered isRegistered} method, the * caller's permissions must imply {@link * MBeanPermission#MBeanPermission(String,String,ObjectName,String) * MBeanPermission(null, null, name, "isRegistered")}.
