Provides support for RMI Object Activation.

Description

Interface Summary

ActivationInstantiator	An ActivationInstantiator is responsible for creating instances of "activatable" objects.
ActivationMonitor	An ActivationMonitor is specific to an ActivationGroup and is obtained when a group is reported active via a call to ActivationSystem.activeGroup (this is done internally).
ActivationSystem	The ActivationSystem provides a means for registering groups and "activatable" objects to be activated within those groups.
Activator	The Activator facilitates remote object activation.

Class Summary

Activatable	The Activatable class provides support for remote objects that require persistent access over time and that can be activated by the system.
ActivationDesc	An activation descriptor contains the information necessary to activate an object: the object's group identifier, the object's class name, the object's code location (the location of the class), and a "marshalled" object that can contain object specific initialization data.
ActivationGroup	An ActivationGroup is responsible for creating new instances of "activatable" objects in its group, informing its ActivationMonitor when either: its object's become active or inactive, or the group as a whole becomes inactive.
ActivationGroupDesc	An activation group descriptor contains the information necessary to create/recreate an activation group in which to activate objects.
ActivationGroupDesc.CommandEnvironment	Startup options for ActivationGroup implementations.
ActivationGroupID	The identifier for a registered activation group serves several purposes: identifies the group uniquely within the activation system, and contains a reference to the group's activation system so that the group can contact its activation system when necessary. The ActivationGroupID is returned from the call to ActivationSystem.registerGroup and is used to identify the group within the activation system.
ActivationID	Activation makes use of special identifiers to denote remote objects that can be activated over time.

Exception Summary

ActivateFailedException	This exception is thrown by the RMI runtime when activation fails during a remote call to an activatable object.
ActivationException	General exception used by the activation interfaces.
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.
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.

Package java.rmi.activation Description

Provides support for RMI Object Activation. A remote object's reference can be made ``persistent'' and later activated into a ``live'' object using the RMI activation mechanism.
