Upload file without user intervention

Question

I know that there's been some topics like this before but I have more trouble.
My goal is this: I file should be automaticly uploaded to my servlet and the I want the internet browser to handle the response.
Because of the restrictions that lies, I think I need to create a small client program that simulates a post request to my servlet and then somehow make IE handle the response.
I've gotten some source code for the simulation of the post request from previous posts in this forum (see below). I haven't really got it to work but that shouldn't be a big problem. The problem is, how do I get IE to handle the response?
Here's the source code for the java program that simulates the post request:
import java.util.*;
import java.io.*;
import java.net.*;
class FileUpload
  // true globals
  // Anything that's unique will work
  static final String CONTENT_BOUNDARY =
"-----------------------------7d22a63810058e";
  public FileUpload() {
  public static void main (String [] args) {
    // whatever file you care to upload
     String uploadFileName = "/testFile.txt";
     FileInputStream fis1 = null;
     OutputStream os1 = null;
     InputStream is1 = null;
     try
          File file1 = new File(uploadFileName);
          fis1 = new FileInputStream(file1);
          // the URL of your upload application
          URL testPost = new URL("http://localhost:8080/test/ReadFile");
          URLConnection huc1 = testPost.openConnection();
          huc1.setAllowUserInteraction(true);
          huc1.setDoOutput(true); // turns it into a post
          huc1.setRequestProperty("Content-Type", "multipart/form-data;boundary="+CONTENT_BOUNDARY);
          huc1.setRequestProperty("User-Agent", "Mozilla/4.7 [en] (WinNT; U)");
          huc1.setRequestProperty("Accept-Language", "en-us");
          huc1.setRequestProperty("Accept-Encoding", "gzip, deflate");
          huc1.setRequestProperty("Accept",
               "image/gif, image/x-xbitmap,image/jpeg, image/pjpeg, "+
               "application/vnd.ms-excel, application/msword, "+
               "application/vnd.ms-powerpoint, application/pdf, application/x-comet, */*");
          huc1.setRequestProperty("CACHE-CONTROL", "no-cache");
          os1 = huc1.getOutputStream();
          // Field 1 a Field of data
          os1.write(
               (CONTENT_BOUNDARY +
               "\r\n"+
               "Content-Disposition: form-data; name=\"txtTitle\"\r\n\r\nTest"+
               "Segment\r\n"
               ).getBytes());
          // Field 2 - the file, name is "uploadFile"
          os1.write(
               (CONTENT_BOUNDARY + "\r\n" +
               "Content-Disposition: form-data; name=\"source\"; filename=\"" +
               uploadFileName +
               "\"\r\nContent-Type: audio/x-pn-realaudio\r\n\r\n"
               ).getBytes());
          byte [] fileStuff = new byte[512];
          int howMany = -1;
          int totMany = 0;
          howMany = fis1.read(fileStuff, 0, 512);
          while (howMany != -1)
               totMany += howMany;
               os1.write(fileStuff, 0, howMany);
               howMany = fis1.read(fileStuff, 0, 512);
          System.err.println("read " + totMany + " bytes from file, wrote to outputstream.");
          fis1.close();
          fis1 = null;
          os1.write(("\r\n" + CONTENT_BOUNDARY + "--\r\n").getBytes());
          is1 = huc1.getInputStream();
          byte [] urlStuff = new byte[512];
          howMany = is1.read(urlStuff, 0, 512);
          while (howMany != -1)
               System.out.write(urlStuff, 0, howMany);
               howMany = is1.read(urlStuff, 0, 512);
          System.err.println("that was your output.");
          is1.close();
          is1 = null;
          os1.close();
          os1 = null;
     catch (Exception ex)
          System.err.println("Exception: " + ex);
          ex.printStackTrace();
         finally
          if (fis1 != null)
               try
                    fis1.close();
               catch(Exception ok_to_eat)
                 // ok to ignore this
          if (is1 != null)
          try
               is1.close();
          catch(Exception ok_to_eat)
            // ok to ignore this
          if (os1 != null)
               try
                      os1.close();
               catch (Exception ok_to_eat)
            // ok to ignore this
}Any suggestions are highly appreciated.
Thanks / Daniel

Answer 1

The problem is, how do I get IE to handle the response?You can't. The response has to be handled by whatever sent the request.
