File is not uploading at the specific destination?

Question

I just have learned somewhere to upload a file into folder. I followed that tutorial as well and it was working too.

When i give the path C:\MyFile, it's uploading my files.

I'm using a Eclipse IDE, Now i've created a folder inside my project named as files. Unfortunately it's not uploading, you could see a Screenshot that where i've created a folder to upload my files.

enter image description here

and it's not working can you just please help me?

I'm getting an error as:

File not uploaded

Here is my source code of UploadFile.java:

package com.fileupload;

import java.io.File;
import java.io.IOException;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.catalina.ha.backend.Sender;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

public class UploadFile extends HttpServlet {
    private static final long serialVersionUID = 1L;
    private final String UPLOAD_DIRECTORY = "files/";

    protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
    boolean isMultipart = ServletFileUpload.isMultipartContent(request);

    // process only if its multipart content
    if (isMultipart) {
        // Create a factory for disk-based file items
        FileItemFactory factory = new DiskFileItemFactory();

        // Create a new file upload handler
        ServletFileUpload upload = new ServletFileUpload(factory);
        try {
            // Parse the request
            List<FileItem> multiparts = upload.parseRequest(request);

            for (FileItem item : multiparts) {
                if (!item.isFormField()) {
                    String name = new File(item.getName()).getName();
                    item.write(new File(UPLOAD_DIRECTORY + File.separator + name));
                }
            }
        } 
        catch (Exception e) 
        {
            System.out.println("File not uploaded");
        }
    }
}
}

and here is my index.jsp:

<!DOCTYPE html>
<html>
<head>
<title>Ajax File Upload with Progress Bar</title>
<!-- Include jQuery form & jQuery script file. -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.js" ></script>

    <form id="UploadForm" action="UploadFile" method="post"
        enctype="multipart/form-data">
        <input type="file" size="60" id="myfile" name="myfile"> <input
            type="submit" value="Ajax File Upload">

        <div id="progressbox">
            <div id="progressbar"></div>
            <div id="percent">0%</div>
        </div>
        <br />

        <div id="message"></div>
    </form>
</body>
</html>

REMEMBER

When i give the path into UPLOAD_DIRECTORY as C:\Files. then it is working .. But when i create a folder into my eclipse project (See above my screenshot) ..It's saying File not uploaded..

EDITED!!

Now i'm using:

private final String UPLOAD_DIRECTORY =getServletContext().getRealPath("/files/");

But getting error as:

Surely, Help would be appreciated!!

Can you please help me, I'm still having `Null pointer exception`.. I edited my question please see it.. sir. — mohan lal, Dec 31 '14 at 13:04
This is the culprit (as in your question), "*Now I've created a folder inside my project named as `files`*". and this is the answer, "*You should not save uploaded files in the deploy folder*" in the accepted answer in the duplicate link. — Tiny, Dec 31 '14 at 18:20

Use following code to get real path of your directory:

getServletContext().getRealPath("/files/");

For more information about this method you can see BalusC's answer.

if you are calling this method in init() method, call super.init(config); at first line of your init method (recommended) or using following code:

config.getServletContext().getRealPath("/files/");

You, and whoever upvoted this terrible answer and hereby destroyed the credibility of Stack Overflow, please read http://stackoverflow.com/questions/12160639/what-does-mean-in-the-method-servletcontext-getrealpath/12160863#12160863. – BalusC Dec 31 '14 at 12:35
@BalusC: You mead I should flag it as duplicated? – Ali Sepehri.Kh Dec 31 '14 at 12:37
I did the same thing as you told me but now i'm having `Null pointer exception` Error: java.lang.NullPointerException at javax.servlet.GenericServlet.getServletContext(GenericServlet.java:125) at com.fileupload.UploadFile.(UploadFile.java:20) – mohan lal Dec 31 '14 at 12:50
Still Not working!! :( – mohan lal Dec 31 '14 at 13:30
Still getting `Null pointer exception`? Do you override `init(ServletConfig config)`? – Ali Sepehri.Kh Dec 31 '14 at 13:35
@mohanlal: your problem resolved? – Ali Sepehri.Kh Dec 31 '14 at 15:02
Nopes, :( I'm still googling it now :( – mohan lal Dec 31 '14 at 16:45
@mohanlal: Use `getServletContext().getRealPath("/files/");` in `doPost()` method instead of `init()` method. If it works we will change it. – Ali Sepehri.Kh Dec 31 '14 at 17:04
@mohanlal: What is your problem, I'm using it now in my application? Would you please add your updated code to your question (edit your code). – Ali Sepehri.Kh Dec 31 '14 at 17:34
@mohanlal: If your problem doesn't resolve yet inform me. – Ali Sepehri.Kh Jan 01 '15 at 09:43
I'm still having the same problems :( – mohan lal Jan 01 '15 at 15:29
@mohanlal: Edit and update your question, I don't know what are you doing now. – Ali Sepehri.Kh Jan 01 '15 at 15:41
