All Implemented Interfaces:

Serializable

Direct Known Subclasses:

UnknownGroupException, UnknownObjectException

public class ActivationException
extends Exception

General exception used by the activation interfaces.

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "detail 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 ActivationException always throws IllegalStateException.

Since:

1.2
