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
AccessException
is thrown by certain methods of thejava.rmi.Naming
class (specificallybind
,rebind
, andunbind
) to indicate that the caller does not have permission to perform the action requested by the method call.AnAlreadyBoundException
is thrown if an attempt is made to bind an object to a name that already has an associated binding in the registry.AConnectException
is thrown if a connection is refused to the remote host for a remote method call.AConnectIOException
is thrown if anIOException
occurs while making a connection to the remote host for a remote method call.AMarshalException
is thrown if ajava.io.IOException
occurs while marshalling the remote call header, arguments or return value for a remote method call.AMarshalledObject
contains a byte stream with the serialized representation of an object given to its constructor.TheNaming
class provides methods for storing and obtaining references to remote objects in a remote object registry.ANoSuchObjectException
is thrown if an attempt is made to invoke a method on an object that no longer exists in the remote virtual machine.ANotBoundException
is thrown if an attempt is made to lookup or unbind in the registry a name that has no associated binding.TheRemote
interface serves to identify interfaces whose methods may be invoked from a non-local virtual machine.ARemoteException
is 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.There is no replacement for the Security Manager.AServerError
is thrown as a result of a remote method invocation when anError
is thrown while processing the invocation on the server, either while unmarshalling the arguments, executing the remote method itself, or marshalling the return value.AServerException
is thrown as a result of a remote method invocation when aRemoteException
is thrown while processing the invocation on the server, either while unmarshalling the arguments or executing the remote method itself.Deprecated.no replacementAStubNotFoundException
is thrown if a valid stub class could not be found for a remote object when it is exported.AnUnexpectedException
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 thethrows
clause of the method in the remote interface.AnUnknownHostException
is thrown if ajava.net.UnknownHostException
occurs while creating a connection to the remote host for a remote method call.AnUnmarshalException
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 ajava.io.IOException
occurs unmarshalling parameters (on the server side) or the return value (on the client side).
