</div>
<div class="ProfilePicsubmit_div">
<input type="submit" class="Profilpicsubmit_btn" value="Next"/>
</div>
</form>
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
String description = request.getParameter("description"); // Retrieves <input type="text" name="description">
Part filePart = request.getPart("file"); // Retrieves <input type="file" name="file">
String fileName = Paths.get(filePart.getSubmittedFileName()).getFileName().toString(); // MSIE fix.
InputStream fileContent = filePart.getInputStream();
File file = new File("D:\\image123.jpg");
file.createNewFile();
OutputStream stream = new DataOutputStream(new FileOutputStream(file));
IOUtils.copy(fileContent,stream);
