messages - Conditionally display a set of accumulated messages.

Displays a set of messages prepared by a business logic component and stored as an ActionMessages object, ActionErrors object, a String, or a String array in any scope. If such a bean is not found, nothing will be rendered.

In order to use this tag successfully, you must have defined an application scope MessageResources bean under the default attribute name.

locale The session attribute key for the Locale used to select messages to be displayed. If not specified, defaults to the Struts standard value. [RT Expr]
name Name of the bean in any scope under which our messages have been stored. If not present, the name specified by the Globals.ERROR_KEY constant string will be used. [RT Expr]
