public class MultipleAction
extends org.apache.struts.actions.DispatchAction

DispatchAction 처럼 Struts 설정 파일의 action 태그의 parameter 속성 값의 메쏘드를 호출하는 Action. 단 DispatchAction과 달리, 메쏘드 파라미터 구성이 HttpRequest, HttpResponse이며 메쏘드의 Return 값이 돌려 주려는 데이타 값이다.

Forwarding은 요청한 URL의 확장자 부분에 따라 Forwarding이 된다. 이 부분은 Struts 의 설정 중 action의 forward의 이름과 연결되는데, 기본적으로 html, xml, json 이 설정되어 있다. html의 경우 호출한 URL과 동일한 경로에 위치한 jsp 파일이 호출되며, xml은 URL과 같은 경로에 위치한 {호출경로}.xml.jsp 가 호출된다.
