Tomcat의 HttpJspBase 클래스

Soul-Learner 2008. 1. 9. 16:05

톰캣에서 JSP는 서블릿으로 변환되어 실행된다. 이 때 변환된 서블릿 코드를 열어 보면 HttpJspBase 클래스를 상속하고 있는 것을 확인할 수가 있다.

package org.apache.jsp;

import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;

public final class count_jsp extends org.apache.jasper.runtime.HttpJspBase

다음은 apache.org 에서 제공하고 있는 HttpJspBase 클래스의 API Documentation 을 발췌한 것이다.
