Attribute value request.getParameter("name") is quoted with " which must be
escaped when used within the value
3.抛出异常:java.lang.IllegalStateException: getOutputStream() has already been called for this response

4.使用
path=request.getRealPath("");
//java.io.File d=new java.io.File(path);
File d=new File(path);
需要加上
<%@page import="java.io.*" %>
<%@page import="java.io.File" %>
<%@page import="com.jspsmart.upload.*" %>
<jsp:useBean id="the" scope="page" class="com.jspsmart.upload.SmartUpload"/>
