File get currupt if downloaded by response.getOutputStream();

[Pritish Shirsath]

Hi,
I am trying to download file (of any type pdf/rar/any etc...) using following code,
but SOME TIME downloaded file is currupted.

                                                   File file = new File(filePath);
			if (file.exists()) {
				if(isDebugEnabled)
					log.debug("File Found");
			}
			
			String quotes = "\"";  
			attachmentName =  quotes.concat(attachmentName).concat(quotes);

			response.setContentType("application/unknown");
			response.setHeader("Pragma", "public");
			response.setHeader("Cache-Control", "max-age=0");
			response.addHeader("Content-Disposition", "attachment; filename="
					+ attachmentName);

			fileInputStream = new FileInputStream(file);
			OutputStream tempStream = response.getOutputStream();

			if (tempStream instanceof FileOutputStream && tempStream != null) {
				destination = ((FileOutputStream) tempStream).getChannel();
				source = new FileInputStream(file).getChannel();
				destination.transferFrom(source, 0, source.size());
			} else {
				outputStream = tempStream;
			int bytesRead;
			while ((bytesRead = fileInputStream.read()) != -1){
				outputStream.write(bytesRead);
			}
			}

but when I use

       File f1=new File("MyFile");
       OutputStream outputStream=new FileOutputStream(f1);

insted of

   

       OutputStream tempStream = response.getOutputStream();
 

It works, & download file by name "MyFile" in bin of tomcat folder.
but not work with response object.
