Using FormData in servlet

Question

I am having formData that contains a file

Like :

  var files = document.getElementById("uploadfile").files;
  /* Create a FormData instance */
  var formData = new FormData();
  /* Add the file */ 
  var file = files[0];
  alert(file.name);
  formData.append('uploadfile', file, file.name);
  client.open("POST", "fileupload?q="+uploadfile,true);
  client.setRequestHeader("Content-Type", "multipart/form-data");
  client.send(formData);  /* Send to server */

Now i want to use this form data in my servlet fileupload.How to use it their ?Please help.

Please google using "jquery file upload using servlet". And check if the results help you !! — A Paul, Mar 31 '14 at 18:51
1. Don't set the content-type header. 2. Handle it like any other file upload. 3. Is `uploadfile` defined aywhere? — Musa, Mar 31 '14 at 18:51
@APaul No the results their are different from my question.could you please help here? — user3462609, Mar 31 '14 at 19:11
There is only one `uploadfile` identifier in your code. `"fileupload?q="+uploadfile` — Musa, Mar 31 '14 at 19:16
@Musa Oh i was just testing it.I didnt used that q parameter anywhere in my servlet.So not a trouble.Actually I was thinking how to send these files at server end — user3462609, Mar 31 '14 at 19:19

I am giving an example how I handled it in my project. I used doPost function to get it.

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);

Do whatever you want with that item.

}

It gives an exception that org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found – user3462609 Mar 31 '14 at 19:09
http://stackoverflow.com/a/2424824/2599879 this answer also explains in detail how to handle file upload. You can find also necessary jar links in the answer which are commons-fileupload.jar and commons-io.jar – ahmet aydin Mar 31 '14 at 19:58
