servlet and jsp displaying same information?

Currently I am trying to display information from my java servlet over to its related jsp page. However, when I run the program, the expected output of the jsp file is displayed in the servlet directory.

Visually, the Display.jsp page: enter image description here

And \ServerToRun (The Servlet page that should display a blank screen): enter image description here

Thus my question is,

Why is the content of /Display.jsp appearing in /ServerToRun?

Here is the code for doPost() of the ServerToRun class:

protected void doPost(HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {

    CSVFileOperations csvfo = new CSVFileOperations();
    String url = "/Display.jsp";

    response.setContentType("text/html");

    String header = csvfo.getHeaders().remove();
    System.out.println(header);

    request.setAttribute("header", header);

    request.getServletContext().getRequestDispatcher(url).
    forward(request, response);


    }

And the markup for Display.jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>OTS Grief</title>
</head>

<body>

${header}<br>
Test Why is his showing up in ServerToRun?
</body>
</html>

Any help is appreciated.

Is because your servlet is trapping all requests, you should notice which annotation you are putting in your ServerToRun.java class or if you are putting in the display descriptor (web.xml) the annotations of the servlet.

I think I understand your question. You're talking about directories.

In your URL, the path (/Grief_UI/Display.jsp and /Grief_UI/ServletToRun) is not necessary related to folders.

It is a structuring element of the URL. Sometimes you don't even have files that are named like these path elements. The path gets normally processed by a Servlet and the user gets the feeling of using folders, yes, but it is only a description for the localising the resources.

Because from servlet you are redirecting to Display.jsp. Try adding any dynamic content in JSP and execute both, only servlet would be able to display the dynamic content.!
