Gzip with servlet

Question

Hi,
I am facing a problem with servlet which compresses the MS Excel files in gzip format,
when i try opening the Template.gz file using winzip or gzip.exe,it throws me an error as either " invalid zip file" or " archive directory not valid"
Can someone pls help in resolving this porblem,
Its very very urgent for me to solve this problem,
My servlet code snippest is as below,
I am using Microsoft Internet Explorer 6.0 to download template.gz file which supports gzip and deflate formats,
--------TemplateGenerator.java-----------------
public void doPost(HttpServletRequest req, HttpServletResponse res)
String encodings = req.getHeader("Accept-Encoding");
System.out.println(encodings);
res.setHeader("Content-Encoding", "gzip");
res.setHeader("Content-Disposition", "attachment;filename=Templates.gz");
try{
//First create User directory
String dir = "C:/";
String separator = System.getProperty("file.separator");
//Read the files in the current directory and write to zip file
GZIPOutputStream zip = new GZIPOutputStream(res.getOutputStream());
File dir1 = new File(dir);
File[] list = dir1.listFiles();
if(list == null)
System.out.println("No files");
else
for(int k=0;k < list.length; k++)
                                   int filelen = (int)list[k].length();
                                   System.out.println("File Length :"+filelen);
                                   FileInputStream fis = new FileInputStream (list[k]);
                                   byte[] tempfile = new byte[filelen];
                                   int bytesRead = fis.read( tempfile,0,filelen );
                                   // checking bytesRead not shown.
                                   fis.close();
                                   // write the contents into the zip element
                                   zip.write( tempfile , 0, filelen );
                                   zip.finish();
// close the entire zip
zip.flush();
zip.close();
