JSP filepath from servlet filter after deploying in Tomcat

I am trying to get the file paths of various JSP files inside my webapp folder after deploying the project in Tomcat. Here is what my directory structure looks like:

-project 
|-top
||-java
|||-com
||||-...
|||-filter
||||-MyFilter.java
||-webapp
|||-jsp
||||-MyJSP.jsp

So when the code hits my filter, what would the path be to MyJSP.jsp inside of the doFilter() method? I am trying to edit the contents of the file, so I need to be able to do read and write operations.

When I do request.getServletPath(), it shows the path: /jsp/MyJSP.jsp. However, when I try to read using the following code:

String str = "";
BufferedReader br = new BufferedReader(new FileReader("/jsp/MyJSP.jsp"));

while ((str = br.readLine()) != null) {
    System.out.println(str );
}

br.close();

I get a FileNotFoundException. What am I doing wrong? Is that not the actual path of the jsp file after it is deployed in Tomcat?

Also, I noticed some other questions saying put the files in the WEB-INF folder, however, there is nothing in that folder except for web.xml and I am not allowed to put anything in there.

Any help would be appreciated!

You may have to use request.getServletContext().getRealPath("/jsp/MyJSP.jsp").

BufferedReader br = new BufferedReader(new FileReader(request.getServletContext().getRealPath("/jsp/MyJSP.jsp")));
