Package java.rmi

Provides the RMI package.


Interface Summary
Remote The Remote interface serves to identify interfaces whose methods may be invoked from a non-local virtual machine.

Class Summary
MarshalledObject A MarshalledObject contains a byte stream with the serialized representation of an object given to its constructor.
Naming The Naming class provides methods for storing and obtaining references to remote objects in the remote object registry.
RMISecurityManager RMISecurityManager provides an example security manager for use by RMI applications that use downloaded code.

Exception Summary
AccessException An AccessException is thrown by certain methods of the java.rmi.Naming class (specifically bind, rebind, and unbind) and methods of the java.rmi.activation.ActivationSystem interface to indicate that the caller does not have permission to perform the action requested by the method call.
AlreadyBoundException An AlreadyBoundException is thrown if an attempt is made to bind an object in the registry to a name that already has an associated binding.
ConnectException A ConnectException is thrown if a connection is refused to the remote host for a remote method call.
ConnectIOException A ConnectIOException is thrown if an IOException occurs while making a connection to the remote host for a remote method call.
MarshalException A MarshalException is thrown if a occurs while marshalling the remote call header, arguments or return value for a remote method call.
NoSuchObjectException A NoSuchObjectException is thrown if an attempt is made to invoke a method on an object that no longer exists in the remote virtual machine.
NotBoundException A NotBoundException is thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.
RemoteException A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call.
RMISecurityException Deprecated. no replacement.
ServerError A ServerError is thrown as a result of a remote method call if the execution of the remote method on the server machine throws a java.lang.Error.
ServerException A ServerException is thrown as a result of a remote method call if the execution of the remote method on the server machine throws a RemoteException.
ServerRuntimeException Deprecated. no replacement
StubNotFoundException A StubNotFoundException is thrown if a valid stub class could not be found for a remote object when it is exported.
UnexpectedException An UnexpectedException is 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 throws clause of the method in the remote interface.
UnknownHostException An UnknownHostException is thrown if a occurs while creating a connection to the remote host for a remote method call.
UnmarshalException An UnmarshalException can 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 occurs unmarshalling parameters (on the server side) or the return value (on the client side).

Package java.rmi Description

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.
