java : upload files to HTTP server using POST, server code issue?

Question

I am new to java and I have to transfer file from Android application to server. I took help from the link

Uploading files to HTTP server using POST. Android SDK

<?php
$target_path  = "./";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
 echo "The file ".  basename( $_FILES['uploadedfile']['name']).
 " has been uploaded";
} else{
 echo "There was an error uploading the file, please try again!";
}
?>

Its PHP code and works perfectly fine but I have to implement the server side code in Java not in PHP.

I googled and find the code from link enter link description here

InputStream in = request.getInputStream();
        BufferedReader r = new BufferedReader(new InputStreamReader(in));
        StringBuffer buf = new StringBuffer();
        String line;
        while ((line = r.readLine())!=null) {
        buf.append(line);
        }
        String s = buf.toString();

I am new to java so donot know how to write this code. I have NetBeans netbeans-7.1.1-ml-javaee installed.

Can somebody tell me that if this code is correct and how to put it in file or which type of file. I have created project but do not know how to put this code in file.

Edits:

Perfect, it works like charm! Note Download httpcomponents-client-4.1-bin.zip from hc.apache.org/downloads.cgi and add httpclient-4.1.jar, httpcore-4.1.jar and httpmime-4.1.jar to your project.

The Apache Commons FileUpload library should help you process the content of the POST request in Java from a server point of view. It can be integrated with Servlets if required.

In particular, it will process the multipart/form-data content for you (which you would otherwise have to do manually if you were reading the request's InputStream directly line by line).
