    剛學這個的時候仿照孫為琴的書寫的上傳代碼，裏面還有一些其它數據，不需要看，編碼問題業已解決.  孫為琴的書裏（精通struts...那本）的例子也得就很好，感謝孫姐，呵呵。 學struts應該有一本她的書
      

  2.   

    不是阿
    <html:file property="file"/>是上傳文件的控件
      

  3.   

    form里要建一个struts file的set\get然后再建一个vo其中那一个bety[]的set/get，最后通过sql把VO对向传入数据库
      

  4.   

    其实可以看一下struts html.tga的示例就明白了
