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.

A class that encapsulates the error messages being reported by the validate() method of an ActionForm.

An ActionForm is a JavaBean optionally associated with one or more ActionMappings.

An ActionFormBean is the definition of a form bean that is loaded from a <form-bean> element in the Struts configuration file.

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.

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.

A class that encapsulates messages.

A subclass of ActionForward which is designed for use in redirecting requests, with support for adding parameters at runtime.

ActionServlet provides the "controller" in the Model-View-Controller (MVC) design pattern for web applications that is commonly known as "Model 2".

Provide a wrapper around an ActionServlet to expose only those methods needed by other objects.

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.

USAGE NOTE - Since Struts 1.1, the reset method no longer initializes property values to those specified in <form-property> elements in the Struts module configuration file.

Implementation of DynaClass for DynaActionForm classes that allow developers to define ActionForms without having to individually code all of the classes.

Thrown when a token generated by the Cancel tag is found in the request, but the cancellable property for the Action Mapping is not set.

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).

RequestProcessor contains the processing logic that the ActionServlet performs as it receives each servlet request from the container.
