文件上传为什么没有实现

<!DOCTYPE html>



Insert title here



请选择文件:


<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="org.lxh.smart.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">



Insert title here


<% SmartUpload smart = new SmartUpload() ;
smart.initialize(pageContext) ; // 初始化上传操作
smart.upload() ; // 上传准备
smart.save("upload") ; //文件保存
%>
