编译出来之后 JSP脚本方式无表达.
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<%!//返回九九乘法表对应的HTML代码.通过表达式来调用,在页面上显示
String printMultiTable1()
{
String s = "";

{
s+=i+"*"+j+"="+(i*j)+" ";
}
s+="<br>"; //追加换行标签
}
return s;
}
//JSP内置out对象,使用脚本方式调用,打印九九乘法表
void printMultiTable2(JspWriter out) throws Exception
{
String s = "";
for(int i=1;i<=9;i++)
{
for(int j=1; j<=i;j++)
{
s+=i+"*"+j+"="+(i*j)+" ";
}
out.println("<br>"); //追加换行标签
}
}
%>
This is my JSP page.<br>

<hr>
<%=printMultiTable1() %>

第二个方式表达不出来
