include 액션 태그를 이용하여 페이지를 합쳐줍니다.


template에서 실행한 첫 화면입니다.

인기 상품을 눌렸을 때의 화면입니다. 인기 상품을 눌리면 주소값에 '?page=bestitem'이 추가 되신 걸 볼 수 있습니다.


이 화면은 신상품을 눌렸을 때의 화면입니다. 인기 상품을 눌리면 주소값에 '?page=newitem'이 추가 되신 걸 볼 수 있습니다.


여기서 가장 중요한 건  left.jsp와 template.jsp입니다.

편의상 같은 jsp로 했지만  각각의 location 부분에  다른 파일을 넣어도 됩니다.
