      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`.

- - ### Field Detail

    - #### 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 Detail

    - #### 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 Detail

    - #### getMessage

          public String getMessage()

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

      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`.
