jsp 내장 객체
1. HTTP 프로토콜 관련 메소드 (testjsp.jsp)
<%@ page import="java.util.Date" language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Request HTTP</title>
</head>
<body>
<%
Date time = new Date();
out.println(time);
out.println("Hello JSP! <p>");
out.println("인코딩 request.getCharacterEncoding() : " + request.getCharacterEncoding() + "<br/>");
out.println("요청 정보 길이 request.getContentLength() : " + request.getContentLength() + "<br/>");

out.println("URL 경로 request.getRequestURL() : " + request.getRequestURL() + "<br/>");
out.println("서버이름 request.getServerName() : " + request.getServerName() + "<br/>");
out.println("포트 request.getServerPort() : " + request.getServerPort() + "<br/>");
%>
</body>
</html>
2. Parameter 관련 메소드
3. Header 관련 메소드 (form1.jsp, getParameter.jsp)
form1.jsp에서 getParameter.jsp 를 불러온다.
<%@ page language="java" contentType="text/html; charset=UTF-8"

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<body>
<form action="getParameter.jsp" method="get">

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@page import="java.util.Enumeration"%><html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Request Parameter, Header</title>
</head>
<body>
<%
String name, familyname;
name = request.getParameter("name");
familyname = request.getParameter("familyname");
out.println("당신의 이름은 " + familyname + name + "입니다. ");
Enumeration e = request.getHeaderNames();
String head;
while(e.hasMoreElements()) {
head = (String)e.nextElement();
out.println(head + " : " + request.getHeader(head) + "<br/>");
}
%>
</body>
</html>
브라우저 인코딩 설정을 해줘야 할 경우
<% request.setCharacterEncoding("euc-kr"); %>
한글문제는 UTF-8로 해결. tomcat의 server.xml의 URIEncoding설정을 UTF-8로 하는것을 잊지 말아야 한다.
