실질적으로 어떻게 동작하는지
jsp파일을 컴파일하면 java파일이 되는건 알지..
어떻게 java파일로 변환되는지 보면..
C:\Java\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\webdev\org\apache\jsp\beans 보면
클래스 파일이 따로따로 만들어져있지. 각각의 페이지인거야. 변수값 공유 같은건 당연히 안되지.. 완전히 모듈화된거지..
다른 방법은 jsp자체에서 include tag를 쓰는 방법이 있지..
content.jsp, main.jsp, menu.jsp, top.jsp 를 /webdev/WebContent/basic 에 복사하고.. main.jsp 수정

C:\Java\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\webdev\org\apache\jsp\basic 보면
main_jsp.java하나뿐이네..
모듈화는 아니지만 변수를 공유한다던가 하는게 쉽지..

HTML자체에서도 프레임을 나눌 수 있었어 frame tag로
근데 HTML5부터는 frame이 없어져 버렸어..
