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
