Activate the object, associated with the given activation identifier. The activator looks for the ActivationDescriptor for the passed identifier, determines the object activation group and initiates object recreation either via ActivationInstantiator or via Class.newInstance().

Parameters:

id - the identifier of the object to activate.

force - if true, the activator always contacts the group to obtain the reference. If false, it may return the cached value.

Returns:

the activated remote object (its stub).

Throws:

UnknownObjectException - if the object with this id is unknown

ActivationException - if the activation has failed due other reason

RemoteException - if the remote call has failed.
