Garbage value while downloading .doc through JSP

Hi,

I am trying to upload and download documents in DB through JSP. For this purpose I use a table with BLOB data type and store byte array in it. Problem is, code is working fine for pdf, txt and jpeg. But in the case of .doc a document with lots of garbage character is getting generated.

To pin point the problem, I removed the part, which was used to store and retrieve byte array from DB. Now I am trying to write byte array in output stream, in the page used to upload file itself. But still i am getting a .doc with garbage value.

My current code looks like:

try{
        MultipartFormDataRequest mrequest = new MultipartFormDataRequest(request);
        java.util.Hashtable files = mrequest.getFiles();
    if ((files != null) || (!files.isEmpty())){
   UploadFile file1 = (UploadFile) files.get("uploadFile");
  String fileName = file1.getFileName();
   byte[] byteArray  = file1.getData();
  if(byteArray != null )
    {
 response.setHeader("Expires", "0");
response.setHeader("Cache-Control","must-revalidate, post-check=0,pre-check=0");
response.setHeader("Pragma", "public");
response.setHeader("Pragma", "no-cache"); //HTTP 1.0
response.setDateHeader("Expires", 0); //prevents caching at the proxy
response.setHeader("Cache-Control", "no-cache"); //HTTP 1.1
response.setHeader("Cache-Control", "max-age=0");
response.setContentType("application/octet-stream");
response.setHeader("Content-disposition", "inline; filename=uploadedFile.doc");
int i = 0;
response.getOutputStream().write(byteArray);
response.getOutputStream().flush();

}

}
       catch(Exception e){
      e.printStackTrace();
    }

Please suggest to debug..!!

Thanks :)

That is your first mistake. JSP is unsuitable for this task. You should be using a servlet.

Please read this article ti understand why JSP is poor choice for this task.
