my web application aim is to download the data from mysql to excel sheet . but using internet explorer browser if iam downloading the data to excel sheet iam able to download the empty excel sheet ie,, iam not able to see the data.
but the same application if iam using mozilla firefox browser iam able to download the excel sheet with data.
i want to download the data by using both browsers.

iam displaying the headers and content types

response.reset();
byte[] blobdata1 = wb1.getBytes();
response.setContentType("application/vnd.ms-excel: xls, xlb: Microsoft Excel Document");
response.setHeader("Content-Disposition", "inline; filename="+" Excel123"+".xls");
response.setDateHeader("max-age", 0);
response.setHeader("cache-control", "no-cache");
response.setHeader("Content-Encoding", "en-US");
response.setHeader("Connection", "keep-alive");
response.setHeader("Expires", "0");
response.setHeader("Pragma", "no-cache");
OutputStream out = response.getOutputStream();
int off = 0;
int l = (int) wb1.getBytes().length;
out.write(blobdata1, off, l);
out.flush();
out.close();

Needed suggestions

Ain't too sure, but you could try setting the following for the Content-type header and see if it works:

application/msexcel
application/x-msexcel
application/ms-excel

Browsers have a weird way of being touchy about what one sets for the Content-type header.
Also as I see, you haven't set the Content-length header. Set it to the value of blobdata1.length
 
It is sorta covered in the JavaRanch Style Guide.
