[Muhammad Zeeshan Iqbal]

Hello,


Language= Java;
Platform= Linux;
Application= Web
I have help excel file. I download it using FileInputStream .
When it is downloaded from solaris or widows platform it is correct.
But when it is downloaded from Linum platform it becomes corrupted.

        
PrintWriter out = new PrintWriter(response.getOutputStream());
response.setContentType("application/excel");
response.setHeader("Content-Disposition", "attachment; filename=\a.xls\");
//Sending the file
    int iRead;
    FileInputStream stream = null;
    File f = new File("a.xls");
    stream = new FileInputStream(f);
//Writing the stream values 
    while ((iRead = stream.read()) != -1)
    out.write(iRead);
//Flush the output
    out.flush();

Kindly, provide me solution.
