http://localhost/Resources/images/msg.jpg

You can get the root of your deployed application with

String root = getServletContext().getRealPath("/");

This will be the equivalent of the resources directory of your source code. Add the filepath of where you want your image to be. i.e.

String filePath = root + "images/msg.jpg";

Then you can created your writer from that path

BufferedWriter writer = new BufferedWriter(new FileWriter(filepath);
writer.write(objectToWrite);//or similar

You can then access the resulting file with

getServletContext().getResource(filePath); // as URL or
getServletContext().getResourceAsStream(filePath); // as InputStream
