<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'index.jsp' starting page</title>
    
  </head>
  
  <body>

  </body>
</html>

 

 

2. 输出字母表

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'index.jsp' starting page</title>
    
  </head>
  
  <body>
    <% for(char c='A';c<='Z';c++)
    out.print(c+"("+(char)(c+32)+")"+","); %>
  </body>
</html>

 

 

3．输出99乘法表

 

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
    String path = request.getContextPath();
    String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()

<body>
    <%
        for (int j = 1; j <= 9; j++) {
            for (int i = 1; i <= j; i++) {
                int n = i * j;
                out.print(i + "*" + j + "=" + n + "");
            }
            out.print("<br>");
