Question

jsp 表单上传 出错 com.jspsmart.upload.SmartUpload cannot be resolved to a type 何解呢。

<%@ page contentType="text/html;charset=UTF-8"%>
<%@ page import="java.sql.*"%>
<%@ page import="com.jspsmart.upload.*" %>

<%@ page import="java.io.*,java.awt.Image,java.awt.image.*,com.sun.image.codec.jpeg.*,java.sql.*,java.util.*"%>

//实例化上载bean
com.jspsmart.upload.SmartUpload mySmartUpload=new com.jspsmart.upload.SmartUpload();
//初始化
mySmartUpload.initialize(pageContext);
//设置上载的最大值
mySmartUpload.setMaxFileSize(500 * 1024*1024);
//上载文件
mySmartUpload.upload();
//循环取得所有上载的文件
for (int i=0;i<mySmartUpload.getFiles().getCount();i++){
//取得上载的文件
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(i);
if (!myFile.isMissing())
{
//取得上载的文件的文件名
String myFileName=myFile.getFileName();
//取得不带后缀的文件名
String suffix=myFileName.substring(0,myFileName.lastIndexOf('.'));

有SmartUpload.class的.用的jspsmartupload.jar组件。网上下的。理论上应该没有问题。。。
<form name="form1" method="post" enctype="multipart/form-data" action="action11.jsp"> 没有问题
