2.smartupload上传文件并附text域的值的汉字解决办法(注意是:WAP,XHTML或XML中,HTML中则不要转换)
<%@ page contentType="application/vnd.wap.xhtml+xml;charset=UTF-8" import="javax.servlet.*,com.framework.*,com.jspsmart.upload.*, java.util.*,java.lang.*"%><?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Wap2.0上传文件并同时发表文章</title>
</head>
<body>

<%
// 初始化
final int MaxFileSize=1024000*4; //上传文件大小限制
String ErrMsg=null; //错误信息
boolean ERR=false; //错误标志
com.jspsmart.upload.SmartUpload mySmartUpload=new com.jspsmart.upload.SmartUpload();
mySmartUpload.initialize(pageContext);

// 上传文件
mySmartUpload.upload();

String authorName=mySmartUpload.getRequest().getParameter("authorName");
out.println(".authorName="+new String(java.net.URLDecoder.decode(_authorName,"utf-8").getBytes("gbk") ));
