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 | An encapsulation of an individual error 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. |
ActionErrors | A class that encapsulates the error messages being reported by
the validate() method of an ActionForm . |
ActionException | An ActionException represents a potential exception
that may occur during delegation to an Action class. |
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. |
ActionFormBeans | Encapsulate a collection of ActionFormBean objects that can be
administered and searched, while hiding the internal implementation. |
ActionForward | An ActionForward represents a destination to which the
controller servlet, ActionServlet , might be directed to
perform a RequestDispatcher.forward() or
HttpServletResponse.sendRedirect() to, as a result of
processing activities of an Action class. |
ActionForwards | Encapsulate a collection of ActionForward objects that can be
administered and searched, while hiding the internal implementation. |
ActionMapping | An ActionMapping represents the information that the
controller servlet, ActionServlet , knows about the mapping
of a particular request to an instance of a particular action class. |
ActionMappings | Encapsulate a collection of ActionMapping objects that can be
administered and searched, while hiding the internal implementation. |
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. |
ActionMessages | A class that encapsulates messages. |
ActionMessages.ActionMessageItem | This class is used to store a set of messages associated with a
property/key and the position it was initially added to list. |
ActionServlet | ActionServlet represents the "controller" in the
Model-View-Controller (MVC) design pattern for web applications that is
commonly known as "Model 2". |
ActionServletWrapper | Provide a wrapper around an ActionServlet to expose only
those methods needed by other objects. |
DynaActionForm | Specialized subclass of ActionForm that allows the creation
of form beans with dynamic sets of properties, without requiring the
developer to create a Java class for each type of form bean. |
DynaActionFormClass | Implementation of DynaClass for
DynaActionForm classes that allow developers to define
ActionForms without having to individually code all of the classes. |
ExceptionHandler | An ExceptionHandler is configured in the Struts configuration file to handle a specific
type of exception thrown by an Action's execute method. |
ForwardingActionForward | A subclass of ActionForward that defaults the
redirect attribute to false . |
RedirectingActionForward | A subclass of ActionForward that defaults the
redirect attribute to true . |
RequestActionMapping | Subclass of ActionMapping that defaults the form bean
scope to request . |
RequestProcessor | RequestProcessor contains the processing logic that
the Struts controller servlet performs as it receives each servlet request
from the container. |
SessionActionMapping | Subclass of ActionMapping that defaults the form bean
scope to session . |
