- 예: image/image1.jpg, image/image2.jpg

- jsp 파일: <img src="./image/image1.jpg">


↓↓↓↓↓↓↓↓↓


1. www.localhost:8080/프로젝트명/Image.action

2. /* -> struts2 -> org.apache.struts2.dispatcher.FilterDispatcher 실행

3. struts.xml 파일을 찾아서 Image라는 네임의 액션을 찾는다

4. 그 액션에 class 속성이 있다면

4-1. 클래스의 객체를 하나 생성한다

4-2. 객체.execute(); 실행한다 

5. 그 액션에 class속성과 method 속성이 있다면 method를 실행한다.

6. return "success" 라면

<result name="success"> /~~.jsp 보여준다 </result>

7. return "false" 라면

}


※ 리턴 값을 succ로 하면 <result name="succ">/DefaultAction.jsp</result> 화면이 뜨고,

    리턴 값을 fail로 주면 <result name="fail">/study.jsp</result> 화면으로 실행된다.
