  String   path=dd.getUrl();
  //path= "upfiles/1.doc ";
    mySmartUpload.initialize(pageContext);
    mySmartUpload.setContentDisposition(null);
    mySmartUpload.downloadFile(path);
   
%>
错误：
getOutputStream()   has   already   been   called   for   this   response
我想按资源的id来查找资源位置的方式来提供下载，可是不行，但去掉注释那一行就可以了，那就实现不了我想的功能了，痛苦，，，请高手指点下，谢谢

把注释去掉，然后输出path，看处理后的path到底指向哪去了

应该是文件路径问题，你用console输出调试下
