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:

1.1

`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis, int nanos)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Field Details

detail

public Throwable detail

The cause of the remote exception.

This field predates the general-purpose exception chaining facility. The Throwable.getCause() method is now the preferred means of obtaining this information.

Constructor Details

RemoteException

public RemoteException()

Constructs a RemoteException.

RemoteException

public RemoteException(String s)

Constructs a RemoteException with the specified detail message.

Parameters:: s - the detail message

RemoteException

public RemoteException(String s, Throwable cause)

Constructs a RemoteException with the specified detail message and cause. This constructor sets the detail field to the specified Throwable.

Parameters:: s - the detail message; cause - the cause

Method Details

getMessage

public String getMessage()

Returns the detail message, including the message from the cause, if any, of this exception.

Overrides:: getMessage in class Throwable
Returns:: the detail message

getCause

public Throwable getCause()

Returns the cause of this exception. This method returns the value of the detail field.

Overrides:: getCause in class Throwable
Returns:: the cause, which may be null.
Since:: 1.4
