Interface MBeanServer
-
All Superinterfaces:
-
MBeanServerConnection
-
All Known Subinterfaces:
-
MBeanServerForwarder
-
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
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
MBeanServerFactory
class applies security checks to its methods, as follows.
First, if there is no security manager (
System.getSecurityManager()
is null), then no checks are made.
Assuming there is a security manager, the checks are made as detailed below. In what follows, className is the string returned by
MBeanInfo.getClassName()
for the target MBean.
If a security check fails, the method throws
SecurityException
.
For methods that can throw
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
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
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
Query.attr(String)
,
Query.attr(String,String)
, and
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
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")
.
