Package org.apache.struts.action

Interface Summary
PlugIn A PlugIn is a configuration wrapper for a module-specific resource or service that needs to be notified about application startup and application shutdown events (corresponding to when the container calls init and destroy on the corresponding ActionServlet instance).

Class Summary
Action An Action is an adapter between the contents of an incoming HTTP request and the corresponding business logic that should be executed to process this request.
ActionError Deprecated. Please use ActionMessage instead, deprecated since 1.2.0.
ActionErrors A class that encapsulates the error messages being reported by the validate() method of an ActionForm.
ActionForm An ActionForm is a JavaBean optionally associated with one or more ActionMappings.
ActionFormBean An ActionFormBean is the definition of a form bean that is loaded from a <form-bean> element in the Struts configuration file.
ActionForward An ActionForward represents a destination to which the controller, RequestProcessor, might be directed to perform a RequestDispatcher.forward or HttpServletResponse.sendRedirect to, as a result of processing activities of an Action class.
ActionMapping An ActionMapping represents the information that the controller, RequestProcessor, knows about the mapping of a particular request to an instance of a particular Action class.
ActionMessage An encapsulation of an individual message returned by the validate method of an ActionForm, consisting of a message key (to be used to look up message text in an appropriate message resources database) plus up to four placeholder objects that can be used for parametric replacement in the message text.
