getAction

public org.apache.struts.action.Action getAction(javax.servlet.http.HttpServletRequest request,
                                                 org.apache.struts.action.ActionMapping mapping,
                                                 org.apache.struts.action.ActionServlet servlet)
                                          throws org.picocontainer.PicoCompositionException

Gets the Action specified by the mapping type from a PicoContainer. The action will be instantiated if necessary, and its dependencies will be injected. The action will be instantiated via a special PicoContainer that just contains actions. If this container already exists in the request attribute, this method will use it. If no such container exists, this method will create a new Pico container and place it in the request. The parent container will either be the request container, or if that container can not be found the session container, or if that container can not be found, the application container. If no parent container can be found, a PicoCompositionException will be thrown. The action path specified in the mapping is used as the component key for the action.

Parameters:

request - the Http servlet request.

mapping - the Struts mapping object, whose type property tells us what Action class is required.

servlet - the Struts ActionServlet.

Returns:

the Action instance.

Throws:

org.picocontainer.PicoCompositionException - if the mapping type does not specify a valid action.

org.picocontainer.PicoCompositionException - if no request, session, or application scoped Pico container can be found.
