JSP入门的简单学习

我的第一个JSP文件是非常简单的JSP,如下:

<%@page import="java.util.Date"%>

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

<head>

</head>

<body>

<%="hello" %>

</body>

</html>

我使用的是Tomcat7.0服务器,加载到Eclipse后,会编译我上面的JSP文件,把该JSP文件通过编译器编译成一个

Servlet的java文件,如下图:

package org.apache.jsp;

import javax.servlet.*;

import javax.servlet.http.*;

import javax.servlet.jsp.*;

import java.util.Date;

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

implements org.apache.jasper.runtime.JspSourceDependent {

private static final javax.servlet.jsp.JspFactory _jspxFactory =

javax.servlet.jsp.JspFactory.getDefaultFactory();

private static java.util.Map<java.lang.String,java.lang.Long> _jspx_dependants;

private javax.el.ExpressionFactory _el_expressionfactory;

private org.apache.tomcat.InstanceManager _jsp_instancemanager;

public java.util.Map<java.lang.String,java.lang.Long> getDependants() {

return _jspx_dependants;

}

public void _jspInit() {

_el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory();

_jsp_instancemanager = org.apache.jasper.runtime.InstanceManagerFactory.getInstanceManager(getServletConfig());

}

public void _jspDestroy() {

}

public void _jspService(final javax.servlet.http.HttpServletRequest request, final javax.servlet.http.HttpServletResponse response)

throws java.io.IOException, javax.servlet.ServletException {

final javax.servlet.jsp.PageContext pageContext;

javax.servlet.http.HttpSession session = null;

final javax.servlet.ServletCo
