How to get the absolute path of a file in my project (and not of a file stored in a temporary folder)

I am using:

I have a JSON file stored in the ./WebContent folder. I am trying to get the absolute path of the JSON file in this way:

ServletContext sc = request.getSession().getServletContext();


    //String absolutePath = "/Users/kazuhira/Documents/MAC_workspace/lab2_calendario/WebContent/Database/Events.json";
    String relativePath = "eventsBackup.json";
    String filePath = sc.getRealPath(relativePath);

    System.out.println("(saverServlet): the path of the file is "+filePath);
    //System.out.println("(saverServlet): the path of the file is "+absolutePath);

    //File file = new File(absolutePath);
    String content = request.getParameter("jsonEventsArray");

    try (FileOutputStream fop = new FileOutputStream(file)) {
        System.out.println("(saverServlet): trying to access to the file"+filePath);
        // if file doesn't exists, then create it
        if (!file.exists()) {
            System.out.println("(saverServlet): the file doesn't exists");
            file.createNewFile();
            System.out.println("(saverServlet): file "+filePath+" created");
        }

        System.out.println("(saverServlet): writing on the file "+filePath);

        // get the content in bytes
        byte[] contentInBytes = content.getBytes();

        fop.write(contentInBytes);
        fop.flush();
        fop.close();

        System.out.println("(saverServlet): events backup done");

    } catch (IOException e) {
        e.printStackTrace();
    }

and the file path reconstructed from the relativePath is:

/Users/kazuhira/Documents/MAC_workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/lab2_calendario/testJson.txt

Why String filePath = sc.getRealPath(relativePath); generates a path on a temporary folder? In which way I can configure the context on the "real" json file (the same I create in the project)?

I suppose Tomcat is working in a temporary context, why? There's a way to tell him to use the same folder of the project?

Yes, you can by changing an option in your Server configuration in Eclipse

enter image description here

Select the second option in the radio button list :)
