弄完之后出现这个错误是怎么回事！！
SmartUpload su = new SmartUpload(); 
// 初始化 su.initialize(pageContext); 
// 设定contentDisposition为null以禁止浏览器自动打开文件， 
//保证点击链接后是下载文件。若不设定，则下载的文件扩展名为 su.setContentDisposition(null); // 下载文件 
su.downloadFile("D://workspace/Car/WebRoot/upload/cars.xml");

调用getOutputStream() 这个方法的那些代码看看
