| java.rmi |
Provides the RMI package. RMI is Remote Method Invocation. It is a
mechanism that enables an object on one Java virtual machine to invoke
methods on an object in another Java virtual machine. Any object that
can be invoked this way must implement the Remote interface. When such
an object is invoked, its arguments are ``marshalled'' and sent from the
local virtual machine to the remote one, where the arguments are
``unmarshalled.'' When the method terminates, the results are
marshalled from the remote machine and sent to the caller's virtual
machine. If the method invocation results in an exception being
thrown, the exception is indicated to caller.
@since JDK1.1

| java.rmi.activation |
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.
@since 1.2

| java.rmi.dgc |
Provides classes and interface for RMI distributed
garbage-collection (DGC). When the RMI server returns an object to
its client (caller of the remote method), it tracks the remote
object's usage in the client. When there are no more references to the
remote object on the client, or if the reference's ``lease'' expires and
not renewed, the server garbage-collects the remote object.
@since JDK1.1
|
| java.rmi.registry |
Provides a class and two interfaces for the RMI registry.
A registry is a remote object that maps names to remote objects. A
server registers its remote objects with the registry so that they can
be looked up. When an object wants to invoke a method on a remote
object, it must first lookup the remote object using its name. The
registry returns to the calling object a reference to the remote
object, using which a remote method can be invoked.
