Sending a ZIP file in Servlet response

[trupti nigam]

In my module, I create a file, then ZIp it. I want to send this zipped file in servlet response.
Here is what I do in my code.

public static final String DEFAULT_CONTENT_TYPE = "application/octet-stream";
public static final int LENGTH_OF_ZIPDATA = 2048;

private void sendFile(HttpServletResponse response,ZipOutputStream out,String fileName)
    {
       response.setContentType(DEFAULT_CONTENT_TYPE);
       response.setContentLength(LENGTH_OF_ZIPDATA);
       response.setHeader("Content-Disposition","attachment;filename=\"" + fileName + "\"");
       try{
        ServletOutputStream op = response.getOutputStream();
        op.write((out.toString()).getBytes());
        op.flush();

       }catch(IOException ioe)
       {
           ioe.printStackTrace();
       }
    }

How do I send the ZipOutputStream in the response. The way I am sending it is incorrect cause converting it to string will not help in this case. I am not sure how to achieve this. Need some pointers.
Thanks,

I think I got the answer to my above question. This is how I achieved it.

 private void sendFile(HttpServletResponse response,String fileName)
    {
       response.setContentType("application/zip");
       response.setContentLength(LENGTH_OF_ZIPDATA);
       response.setHeader("Content-Disposition","attachment;filename=\"" + fileName + "\"");
       try{
        File f = new File(fileName);
        byte[] arBytes = new byte[(int)f.length()];
        FileInputStream is = new FileInputStream(f);
        is.read(arBytes);
        ServletOutputStream op = response.getOutputStream();
        op.write(arBytes);
        op.flush();

       }catch(IOException ioe)
       {
           ioe.printStackTrace();
       }
    }

thanks,
