    public class EventsException
extends java.lang.Exception
    The EventsException class is the base exception that all Common Event Infrastructure exceptions should inherit from. This class provides support for exception chaining semantics and localized (language-specific) messages.

    Exceptions that subclass this exception need to add only the various constructors and inherit everything else from this class.

    An EventsException contains the following components:

    • A key, which selects the text to be displayed from the message file. (Separating the text from the classes that use the text. This enables the text to be translated into different national languages.)
    • A message file, which contains a set of messages that might be displayed. Entries in the message file are stored as key=value pairs.
    • A set of Objects which can be inserted into the message text. These parameters are required only if the message expects them. These Objects are processed according to the rules of the java.text.MessageFormat class.
    • A nested Exception whose message text will be displayed with the text of this EventsException.
