Description
| 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 | 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 | Deprecated. Replaced by org.apache.struts.config.ExceptionConfig |
| 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 | Deprecated. Replaced by collection of FormBeanConfig instances
in ModuleConfig |
| 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 | Deprecated. Replaced by collection of ForwardConfig instances in
ModuleConfig and ActionConfig |
| 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 | Deprecated. Replaced by collection of ActionConfig instances in
ModuleConfig |
| 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. |
| 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. |
The action package is the core of the struts framework, providing the "Controller" aspect of a MVC model.
