I have just finished a project recently, do it with struts1.1. Never understand, to skilled, rely on some documents of 9CBS. But there is not necessarily suitable for yourself, so I will take some things I have to give you some things, and I will communicate with each other. If you have a good way, you can contact me. MSN: WHW_DREAM (AT) Hotmail.comStruts Upload this text is Struts1.1 org.Apache.Struts.upload.formfile class. Very convenient, don't write it yourself. You don't have to write a JSP to call JSPSmartupLoad to get it. Select the upload file page: selfile.jsp
