jsp下载文件的问题

小弟想在jsp中点击1个按钮下载文件，点击“下载”按钮后，成功弹出下载对话框，“打开”和“保存”都没报错，但是点击“取消”，servlet就有错误发生： “Outputstream encountered error during write”,意思是说在写文件的时候流发生错误。

请问如何解决这个问题，十分感谢！！！

servlet中的代码如下：

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String fileName = "D:\\test.csv";
FileInputStream fileInputStream = new FileInputStream(fileName);
BufferedInputStream bufferedInputStream = new BufferedInputStream(fileInputStream);
response.reset();

response.setContentType("text/html;");
response.setHeader("Content-Disposition", "attachment;filename="+fileName);
OutputStream outputStream = response.getOutputStream();
byte[] b = new byte[1024];
int len = 0;
while((len=bufferedInputStream.read(b)) != -1){
outputStream.write(b,0,len);
}
outputStream.close();
bufferedInputStream.close();
fileInputStream.close();
}
