注意：第一個轉換，"ISO-8859-1"————"UTF-8" UTF-8是根據你自己的編碼來處理
第二個轉換，"gb2312"————"iso-8859-1" 你就不要改變了，不管你是什麼編碼，都這麼處理就是了，只要你的客戶用的是中文的操作系統，呵呵
配置文件的內容

在配置文件中限制上傳文件的格式
< action name ="fileUpload" class ="tutorial.FileUploadAction" >
< interceptor-ref name ="fileUpload" >
< param name ="allowedTypes" >
image/bmp,image/png,image/gif,image/jpeg
</ param >
</ interceptor-ref >
< interceptor-ref name ="defaultStack" />
< result name ="input" > /FileUpload.jsp </ result >
< result name ="success" > /ShowUpload.jsp </ result >
</ action >
