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.
Interface Summary Interface Description RemoteThe
Remoteinterface serves to identify interfaces whose methods may be invoked from a non-local virtual machine.
Class Summary Class Description MarshalledObject<T>A
MarshalledObjectcontains a byte stream with the serialized representation of an object given to its constructor.
Namingclass provides methods for storing and obtaining references to remote objects in a remote object registry.
Exception Summary Exception Description AccessExceptionAn
AccessExceptionis thrown by certain methods of the
unbind) and methods of the
java.rmi.activation.ActivationSysteminterface to indicate that the caller does not have permission to perform the action requested by the method call.
AlreadyBoundExceptionis thrown if an attempt is made to bind an object to a name that already has an associated binding in the registry.
ConnectExceptionis thrown if a connection is refused to the remote host for a remote method call.
ConnectIOExceptionis thrown if an
IOExceptionoccurs while making a connection to the remote host for a remote method call.
MarshalExceptionis thrown if a
java.io.IOExceptionoccurs while marshalling the remote call header, arguments or return value for a remote method call.
NoSuchObjectExceptionis thrown if an attempt is made to invoke a method on an object that no longer exists in the remote virtual machine.
NotBoundExceptionis thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.
RemoteExceptionis the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call.
ServerErroris thrown as a result of a remote method invocation when an
Erroris thrown while processing the invocation on the server, either while unmarshalling the arguments, executing the remote method itself, or marshalling the return value.
ServerExceptionis thrown as a result of a remote method invocation when a
RemoteExceptionis thrown while processing the invocation on the server, either while unmarshalling the arguments or executing the remote method itself.
ServerRuntimeException Deprecated.no replacement StubNotFoundExceptionA
StubNotFoundExceptionis thrown if a valid stub class could not be found for a remote object when it is exported.
UnexpectedExceptionis thrown if the client of a remote method call receives, as a result of the call, a checked exception that is not among the checked exception types declared in the
throwsclause of the method in the remote interface.
UnknownHostExceptionis thrown if a
java.net.UnknownHostExceptionoccurs while creating a connection to the remote host for a remote method call.
UnmarshalExceptioncan be thrown while unmarshalling the parameters or results of a remote method call if any of the following conditions occur: if an exception occurs while unmarshalling the call header if the protocol for the return value is invalid if a
java.io.IOExceptionoccurs unmarshalling parameters (on the server side) or the return value (on the client side).
