우선 JSTL 라이브러리를 여기에서 다운로드한 후에, WEB-INF/lib 디렉토리에 복사한다.
- jstl-api-1.2.jar
- jstl-impl-1.2.jar
그리고 JSTL을 사용하는 JSP 앞쪽에 다음 내용을 추가한다.
<%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
* sql, xml, fmt 태그 등도 비슷한 방법으로 사용한다.
그런데 JSP가 임의의 클래스를 상속하는 경우에는 c:forEach 태그가 정상적으로 동작하지 않을 수 있다. 이를 해결하려면 JSP 상위 클래스에서 ServletConfig를 올바르게 처리해야 한다.
