Reading file with FileInputStream (Servlet) - How to use relative pathing?

[KingdomX]

Hello!

The idea:
Basically i'm trying to read a file and print it on the browser.

The problem:
I got it working but i have a problem that the file path being used is the full path on my computer (D:/Sites/GamersLust/web/html/index.html) and i don't think that's gonna sit well on a live host. I'm using the function from the file located at D:/Sites/GamersLust/web/index.jsp, which is the website's root.
Am i using the wrong method here to do this? I've tried setting the path to:

html/index.html
/html/index.html
./html/index.html
../html/index.html

The code:

    public void doGet(HttpServletRequest req, HttpServletResponse res)
        throws IOException, ServletException
    {
        // output an HTML page
        res.setContentType("text/html");

        // print some html
        PrintWriter out = res.getWriter();

        // print the file
        InputStream in = null;
        try {
            in = new BufferedInputStream
                (new FileInputStream("D:/Sites/GamersLust/web/html/index.html") );
            int ch;
            while ((ch = in.read()) !=-1) {
                out.print((char)ch);
            }
        }
        finally {
            if (in != null) in.close();  // very important
        }
    }

Any ideas and comments are appreciated!

Thanks in advance!

Do what I do (as I can never remember the path).

File f = new File("dummy");
log.debug("file is at " + f.getAbsolutePath());  // Or whatever logging system you have

That'll tell you pretty quickly what your runtime directory is.

Hmmmm, that returned:
file is at C:\Program Files\Apache Software Foundation\Tomcat 7.0\dummy

It's where my server is installed at... Is there a way to get the filepath of the file that's executing the command?

Thanks!

EDIT: Got it, here it is:

        String path = req.getSession().getServletContext().getRealPath("/");

Thanks! Solved!
