Module java.rmi
Package java.rmi
package 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.

ClassDescriptionAn
AccessExceptionis thrown by certain methods of thejava.rmi.Namingclass (specificallybind,rebind, andunbind) to indicate that the caller does not have permission to perform the action requested by the method call.AnAlreadyBoundExceptionis thrown if an attempt is made to bind an object to a name that already has an associated binding in the registry.AConnectExceptionis thrown if a connection is refused to the remote host for a remote method call.AConnectIOExceptionis thrown if anIOExceptionoccurs while making a connection to the remote host for a remote method call.AMarshalExceptionis thrown if ajava.io.IOExceptionoccurs while marshalling the remote call header, arguments or return value for a remote method call.AMarshalledObjectcontains a byte stream with the serialized representation of an object given to its constructor.TheNamingclass provides methods for storing and obtaining references to remote objects in a remote object registry.ANoSuchObjectExceptionis thrown if an attempt is made to invoke a method on an object that no longer exists in the remote virtual machine.ANotBoundExceptionis thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.TheRemoteinterface serves to identify interfaces whose methods may be invoked from a non-local virtual machine.ARemoteExceptionis the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call.Deprecated.Deprecated, for removal: This API element is subject to removal in a future version.This class is only useful in conjunction with the Security Manager, which is deprecated and subject to removal in a future release.AServerErroris thrown as a result of a remote method invocation when anErroris thrown while processing the invocation on the server, either while unmarshalling the arguments, executing the remote method itself, or marshalling the return value.AServerExceptionis thrown as a result of a remote method invocation when aRemoteExceptionis thrown while processing the invocation on the server, either while unmarshalling the arguments or executing the remote method itself.Deprecated.no replacementAStubNotFoundExceptionis thrown if a valid stub class could not be found for a remote object when it is exported.AnUnexpectedExceptionis 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 thethrowsclause of the method in the remote interface.AnUnknownHostExceptionis thrown if ajava.net.UnknownHostExceptionoccurs while creating a connection to the remote host for a remote method call.AnUnmarshalExceptioncan 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 ajava.io.IOExceptionoccurs unmarshalling parameters (on the server side) or the return value (on the client side).
