Class JMXConnectorServer

  • All Implemented Interfaces:
    MBeanRegistration, NotificationBroadcaster, NotificationEmitter, JMXAddressable, JMXConnectorServerMBean
    Direct Known Subclasses:
    RMIConnectorServer


    public abstract class JMXConnectorServer
    extends NotificationBroadcasterSupport
    implements JMXConnectorServerMBean, MBeanRegistration, JMXAddressable

    Superclass of every connector server. A connector server is attached to an MBean server. It listens for client connection requests and creates a connection for each one.

    A connector server is associated with an MBean server either by registering it in that MBean server, or by passing the MBean server to its constructor.

    A connector server is inactive when created. It only starts listening for client connections when the start method is called. A connector server stops listening for client connections when the stop method is called or when the connector server is unregistered from its MBean server.

    Stopping a connector server does not unregister it from its MBean server. A connector server once stopped cannot be restarted.

    Each time a client connection is made or broken, a notification of class JMXConnectionNotification is emitted.

    • Field Detail

      • AUTHENTICATOR

        public static final String AUTHENTICATOR

        Name of the attribute that specifies the authenticator for a connector server. The value associated with this attribute, if any, must be an object that implements the interface JMXAuthenticator.

        Constant Field Values
    • Constructor Detail

      • JMXConnectorServer

        public JMXConnectorServer()

        Constructs a connector server that will be registered as an MBean in the MBean server it is attached to. This constructor is typically called by one of the createMBean methods when creating, within an MBean server, a connector server that makes it available remotely.

      • JMXConnectorServer

        public JMXConnectorServer(MBeanServer mbeanServer)

        Constructs a connector server that is attached to the given MBean server. A connector server that is created in this way can be registered in a different MBean server, or not registered in any MBean server.

        Parameters:
        mbeanServer - the MBean server that this connector server is attached to. Null if this connector server will be attached to an MBean server by being registered in it.
    • Method Detail

      • getMBeanServer

        public MBeanServer getMBeanServer()

        Returns the MBean server that this connector server is attached to.

        Returns:
        the MBean server that this connector server is attached to, or null if it is not yet attached to an MBean server.
      • setMBeanServerForwarder

        public void setMBeanServerForwarder(MBeanServerForwarder mbsf)
        Description copied from interface: JMXConnectorServerMBean

        Inserts an object that intercepts requests for the MBean server that arrive through this connector server. This object will be supplied as the MBeanServer for any new connection created by this connector server. Existing connections are unaffected.

        This method can be called more than once with different MBeanServerForwarder objects. The result is a chain of forwarders. The last forwarder added is the first in the chain. In more detail:

        • If this connector server is already associated with an MBeanServer object, then that object is given to mbsf.setMBeanServer. If doing so produces an exception, this method throws the same exception without any other effect.

        • If this connector is not already associated with an MBeanServer object, or if the mbsf.setMBeanServer call just mentioned succeeds, then mbsf becomes this connector server's MBeanServer.

        Specified by:
        setMBeanServerForwarder in interface JMXConnectorServerMBean
        Parameters:
        mbsf - the new MBeanServerForwarder.
      • getConnectionIds

        public String[] getConnectionIds()
        Description copied from interface: JMXConnectorServerMBean

        The list of IDs for currently-open connections to this connector server.

        Specified by:
        getConnectionIds in interface JMXConnectorServerMBean
        Returns:
        a new string array containing the list of IDs. If there are no currently-open connections, this array will be empty.
      • preRegister

        public ObjectName preRegister(MBeanServer mbs,
                                      ObjectName name)

        Called by an MBean server when this connector server is registered in that MBean server. This connector server becomes attached to the MBean server and its getMBeanServer() method will return mbs.

        If this connector server is already attached to an MBean server, this method has no effect. The MBean server it is attached to is not necessarily the one it is being registered in.

        Specified by:
        preRegister in interface MBeanRegistration
        Parameters:
        mbs - the MBean server in which this connection server is being registered.
        name - The object name of the MBean.
        Returns:
        The name under which the MBean is to be registered.
        Throws:
        NullPointerException - if mbs or name is null.
      • postRegister

        public void postRegister(Boolean registrationDone)
        Description copied from interface: MBeanRegistration
        Allows the MBean to perform any operations needed after having been registered in the MBean server or after the registration has failed.

        If the implementation of this method throws a RuntimeException or an Error, the MBean Server will rethrow those inside a RuntimeMBeanException or RuntimeErrorException, respectively. However, throwing an exception in postRegister will not change the state of the MBean: if the MBean was already registered (registrationDone is true), the MBean will remain registered.

        This might be confusing for the code calling createMBean() or registerMBean(), as such code might assume that MBean registration has failed when such an exception is raised. Therefore it is recommended that implementations of postRegister do not throw Runtime Exceptions or Errors if it can be avoided.

        Specified by:
        postRegister in interface MBeanRegistration
        Parameters:
        registrationDone - Indicates whether or not the MBean has been successfully registered in the MBean server. The value false means that the registration phase has failed.
      • preDeregister

        public void preDeregister()
                           throws Exception

        Called by an MBean server when this connector server is unregistered from that MBean server. If this connector server was attached to that MBean server by being registered in it, and if the connector server is still active, then unregistering it will call the stop method. If the stop method throws an exception, the unregistration attempt will fail. It is recommended to call the stop method explicitly before unregistering the MBean.

        Specified by:
        preDeregister in interface MBeanRegistration
        Throws:
        IOException - if thrown by the stop method.
        Exception - This exception will be caught by the MBean server and re-thrown as an MBeanRegistrationException.
      • postDeregister

        public void postDeregister()
        Description copied from interface: MBeanRegistration
        Allows the MBean to perform any operations needed after having been unregistered in the MBean server.

        If the implementation of this method throws a RuntimeException or an Error, the MBean Server will rethrow those inside a RuntimeMBeanException or RuntimeErrorException, respectively. However, throwing an exception in postDeregister will not change the state of the MBean: the MBean was already successfully deregistered and will remain so.

        This might be confusing for the code calling unregisterMBean(), as it might assume that MBean deregistration has failed. Therefore it is recommended that implementations of postDeregister do not throw Runtime Exceptions or Errors if it can be avoided.

        Specified by:
        postDeregister in interface MBeanRegistration
