I want to upload an image to a disk drive location in future it may be server drive location and it will display the same on a webpage using file path location that should be fetched from the database.
I tried to upload the images to the project directory, but the image file is not getting uploaded. However, when I refresh the project directory it will appear there.
The path I provided is a project location directory.

File directory1 = new File(filePath);
if (directory1.exists()) {} else {
directory1.mkdir();

System.out.println(filePath);

response.sendRedirect("add_new_projects.jsp");
}

}
I expect that the image file should be uploaded to the particular drive location. It may be local or server drive location. That path should be stored in a database and displayed the same on the web page.
