- - ### Uses of ActivationException in java.rmi.activation

    Subclasses of ActivationException in java.rmi.activation
    Modifier and Type | Class and Description
    --- | ---
    `class` | `UnknownGroupException` An `UnknownGroupException` is thrown by methods of classes and interfaces in the `java.rmi.activation` package when the `ActivationGroupID` parameter to the method is determined to be invalid, i.e., not known by the `ActivationSystem`.
    `class` | `UnknownObjectException` An `UnknownObjectException` is thrown by methods of classes and interfaces in the `java.rmi.activation` package when the `ActivationID` parameter to the method is determined to be invalid.

    Methods in java.rmi.activation that throw ActivationException
    Modifier and Type | Method and Description
    --- | ---
    `MarshalledObject<? extends Remote>` | Activator.`activate(ActivationID id, boolean force)` Activate the object associated with the activation identifier, `id`.
    `Remote` | ActivationID.`activate(boolean force)` Activate the object for this id.
    `ActivationMonitor` | ActivationSystem.`activeGroup(ActivationGroupID id, ActivationInstantiator group, long incarnation)` Callback to inform activation system that group is now active.
    `protected void` | ActivationGroup.`activeObject(ActivationID id, MarshalledObject<? extends Remote> mobj)` This protected method is necessary for subclasses to make the `activeObject` callback to the group's monitor.
    `abstract void` | ActivationGroup.`activeObject(ActivationID id, Remote obj)` The group's `activeObject` method is called when an object is exported (either by `Activatable` object construction or an explicit call to `Activatable.exportObject`.
    `static ActivationGroup` | ActivationGroup.`createGroup(ActivationGroupID id, ActivationGroupDesc desc, long incarnation)` Create and set the activation group for the current VM.
    `static ActivationID` | Activatable.`exportObject(Remote obj, String location, MarshalledObject<?> data, boolean restart, int port)` Registers an activation descriptor (with the specified location, data, and restart mode) for the specified object, and exports that object with the specified port.
    `static ActivationID` | Activatable.`exportObject(Remote obj, String location, MarshalledObject<?> data, boolean restart, int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf)` Registers an activation descriptor (with the specified location, data, and restart mode) for the specified object, and exports that object with the specified port, and the specified client and server socket factories.
    `ActivationDesc` | ActivationSystem.`getActivationDesc(ActivationID id)` Returns the activation descriptor, for the object with the activation identifier, `id`.
    `ActivationGroupDesc` | ActivationSystem.`getActivationGroupDesc(ActivationGroupID id)` Returns the activation group descriptor, for the group with the activation group identifier, `id`.
    `static ActivationSystem` | ActivationGroup.`getSystem()` Returns the activation system for the VM.
    `static boolean` | Activatable.`inactive(ActivationID id)` Informs the system that the object with the corresponding activation `id` is currently inactive.
    `boolean` | ActivationGroup.`inactiveObject(ActivationID id)` The group's `inactiveObject` method is called indirectly via a call to the `Activatable.inactive` method.
    `MarshalledObject` | ActivationGroup_Stub.`newInstance(ActivationID id, ActivationDesc desc)` Stub method for `ActivationGroup.newInstance`.
    `MarshalledObject<? extends Remote>` | ActivationInstantiator.`newInstance(ActivationID id, ActivationDesc desc)` The activator calls an instantiator's `newInstance` method in order to recreate in that group an object with the activation identifier, `id`, and descriptor, `desc`.
    `static Remote` | Activatable.`register(ActivationDesc desc)` Register an object descriptor for an activatable remote object so that is can be activated on demand.
    `ActivationGroupID` | ActivationSystem.`registerGroup(ActivationGroupDesc desc)` Register the activation group.
    `ActivationID` | ActivationSystem.`registerObject(ActivationDesc desc)` The `registerObject` method is used to register an activation descriptor, `desc`, and obtain an activation identifier for a activatable remote object.
    `ActivationDesc` | ActivationSystem.`setActivationDesc(ActivationID id, ActivationDesc desc)` Set the activation descriptor, `desc` for the object with the activation identifier, `id`.
    `ActivationGroupDesc` | ActivationSystem.`setActivationGroupDesc(ActivationGroupID id, ActivationGroupDesc desc)` Set the activation group descriptor, `desc` for the object with the activation group identifier, `id`.
    `static void` | ActivationGroup.`setSystem(ActivationSystem system)` Set the activation system for the VM.
    `static void` | Activatable.`unregister(ActivationID id)` Revokes previous registration for the activation descriptor associated with `id`.
    `void` | ActivationSystem.`unregisterGroup(ActivationGroupID id)` Remove the activation group.
    `void` | ActivationSystem.`unregisterObject(ActivationID id)` Remove the activation id and associated descriptor previously registered with the `ActivationSystem`; the object can no longer be activated via the object's activation id.

    Constructors in java.rmi.activation that throw ActivationException
    Constructor and Description
    `Activatable(String location, MarshalledObject<?> data, boolean restart, int port)` Constructs an activatable remote object by registering an activation descriptor (with the specified location, data, and restart mode) for this object, and exporting the object with the specified port.
    `Activatable(String location, MarshalledObject<?> data, boolean restart, int port, RMIClientSocketFactory csf, RMIServerSocketFactory ssf)` Constructs an activatable remote object by registering an activation descriptor (with the specified location, data, and restart mode) for this object, and exporting the object with the specified port, and specified client and server socket factories.
    `ActivationDesc(String className, String location, MarshalledObject<?> data)` Constructs an object descriptor for an object whose class name is `className`, that can be loaded from the code `location` and whose initialization information is `data`.
    `ActivationDesc(String className, String location, MarshalledObject<?> data, boolean restart)` Constructs an object descriptor for an object whose class name is `className`, that can be loaded from the code `location` and whose initialization information is `data`.
