Problem with downloading files

Hi all
I am using the below given code to download files from a remote server through a web page. It works fine with files of size larger than around 10k. But it gives me an error when I try to download files below 10K. I get a pop up error message from IE saying this.
"Internet Explorer cannot download <file> from <server>"
"Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later."
This does not happen in the case or files larger than 10k.
If any of you have any idea why this happens, help me.
Thanks in advance

java.io.File file = new java.io.File("test.txt");
java.io.FileInputStream fileIn = new java.io.FileInputStream(file);
long fileLen = file.length();
int rb = 0;
int tr = 0;
byte bArr[] = new byte[blockSize];
if(contentType == null)
response.setContentType("application/x-msdownload");
else
if(contentType.length() == 0)
response.setContentType("application/x-msdownload");
else
response.setContentType(contentType);
response.setContentLength((int)fileLen);
if(destFileName == null)
response.setHeader("Content-Disposition", "attachment;
filename=".concat(String.valueOf(getFileName("test.txt"))));
else
if(destFileName.length() == 0)
response.setHeader("Content-Disposition", "attachment;");
else
response.setHeader("Content-Disposition", "attachment;
filename=".concat(String.valueOf(destFileName)));
while((long)tr < fileLen)
{
if ((tr+blockSize) < fileLen)
{
rb = fileIn.read(bArr, 0, blockSize);
}
else
{
rb = fileIn.read(bArr, 0, (int)(fileLen-tr));
}
tr += rb;
response.getOutputStream().write(bArr, 0, rb);
}
fileIn.close();

Hiu biju,
i want to a similar activity like u did..i.e downloading a file from a webserver and storing it in a particular directory.
how do i go about doing this in jsp where the file name is shown as a hyperlink also the file is a text file.
Another i would like to know is can i find out whether the download was sucessful or cancelled in between?
Please help me on this
Thanx in advance
