public class RemoteException
extends IOException

A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "wrapped remote exception" that may be provided at construction time and accessed via the public detail field is now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy field."

Invoking the method Throwable.initCause(Throwable) on an instance of RemoteException always throws IllegalStateException.

Since:

JDK1.1
