Iam using java.io.GZIPOutputStream to defalte and download a file from the server.Iam using jsp.The code iam using is: FileInputStream inputStream=new FileInputStream("filename"); GZIPOutputStream zipOutStream = new GZIPOutputStream( response.getOutputStream()); out.clearBuffer(); int c; while ((c=fis.read()) != -1){ zipOutStream.write(c); } out.flush(); out.clear(); The problem is that the files gets downloaded, but it doesn't seem to be a valid archive and it is corrupted. Iam setting the content type as "application/download". Do i have to set any headers for this.    More>>
