求教！想实现上传图片功能，通过String ICP=su.getRequest().getParameter("ICP")无法获取值
我想实现图片上传的功能，但是表单的值一直传递不了，源代码如下（不规范，见谅！）：
register.jsp:
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>

所有的输出都是null，为什么？怎么处理？
[解决办法]
SmartUpload su = new SmartUpload();
su.initialize(pageContext);
su.service(request, response);
su.setTotalMaxFileSize(100000000);
su.setAllowedFilesList("zip,rar");
su.setDeniedFilesList("exe,bat,jsp,htm,html,,");
su.upload();
String ICP=su.getRequest().getParameter("ICP");
String name=su.getRequest().getParameter("name");
String brief=su.getRequest().getParameter("brief");
。。。下面省略
下面这两句话是错误的，不可以这样获取路径名字，要js获取
String certification=su.getRequest().getParameter("certification");
String certification2=su.getRequest().getParameter("certification2");
建议获取上传后的名字
File myFile = su.getFiles().getFile(1);
String str = myFile.getFileName();
这里是SQL版块，建议楼主下次发java那里哦！！！
[解决办法]
<form action="register_deal.jsp" method="post" enctype="multipart/form-data" name="form13" id="form13">
你的action是register_deal.jsp
你的处理页面是deal_register.jsp？
[解决办法]
考察一下这样su.getRequest()获取的request
是不是真正页面请求过来包含数据的request
如果换成隐藏对象request直接获取会是什么结果
[解决办法]
查看你的form是否对应的是这个action
[解决办法]
没用过SmartUpload，帮顶
